Why Do Cats Purr?

If you love cats, their purr is probably one of the most soothing voices in the world for you. Purring from cat is like the essence of satisfaction, but it sounds weird and odd. How does the cat continuously emit a perfect vibration for a few minutes? After decades of research, no one can find out exactly why. But here are some things that we can be sure about.

When the cat is sleeping next to you or is intimate with you, it can often be heard that it emits a continuous purring sound. Most people mistakenly believe that this is the purr cat made while sleeping. In fact, the purring sound is the sound a cat made when its false vocal cords vibrate.

From a medical point of view, the skeleton of the cat’s throat is composed of thyroid cartilage and cricoid cartilage. The laryngeal cavity is divided into three parts, the upper part is the laryngeal vestibule and the trailing edge is the false vocal cord. The cavity between the false vocal cord and the true vocal cord is the second part of the laryngeal cavity. The third part is the cavity between the vocal cords and the cartilage ring, which is very narrow.

A cat’s purr is a sound made by the resonance of laryngeal cavity when the false vocal cords vibrate. In fact, when cats are snoring, they do not fall asleep. Cats do not snore when they are playing, feel nervous and really fall asleep.Only when cats are satisfied, or when they feel relaxed and happy in owner’s arms, will they make a brisk purring sound.

At this point, adult cats and Persian cats are more prominent, while kittens rarely snore. Persian cats snore because of their short nasal passages. Adult cats purr because they are more appreciative of enjoying their lives and understanding humans’ caresses and relatives. Therefore, the most typical explanation for the purr sound is that it is a manifestation of happiness and satisfaction. But cats also purr for many other reasons.

Leslie A. Lyons, an assistant professor at the School of Veterinary Medicine at the University of California, Davis, explains that: “Cats often purr while under duress, such as during a visit to the veterinarian or when recovering from injury. Thus, not all purring cats appear to be content or pleased with their current circumstances.”

In fact, we don’t know why cats make a “purr” sound, but it seems obvious that this sound has multiple effects. Paul Leyhausen, a renowned animal behaviorist who has spent decades studying cats, said that purr is a way for cats to communicate with each other to show that they are not malicious. A recent study found that when a cat needs people to feed it, it emits a special “purr” sound (of course, it often makes a “purr” sound during eating).

Maybe actually the cat purred is not because it was happy, but just consoling itself with the fact that it had to be touched for the 50,000th time on the head by these active people.

In addition, if the cat keeps snoring regardless of the circumstances, it may be a respiratory infection, and don’t be careless about this.

How Much Do You Know About Dog Blood Groups?

Blood types, or blood groups are determined by specific antigens found on the surface of erythrocytes. In humans, there is the ABO system of blood types, whereas dogs have a variety of different blood types. Knowledge of blood types in the different species is important as transfusion of incompatible blood can result in severe hemolytic transfusion reactions and even death, in some instances.

 (blue: blood donors red: blood recipients o: can transfuse x: can not transfuse)

Dog has 13 blood types which are designated by the acronym DEA (dog erythrocyte antigen) and a number (DEA1, DEA2, DEA3 to DEA12). Other than DEA blood types, Dal is another blood type commonly known in dogs.

DEA1 has two subtypes: DEA1.1 and DEA1.2. DEA 1.1 positive is the most common dog blood type, and dogs with this type are considered universal recipients, that is, they can receive blood of any type without expectation of a life-threatening hemolytic transfusion reaction. Dogs that are DEA1.1 negative are universal donors.

Blood from DEA1.1 positive dogs should never be transfused into DEA1.1 negative dogs. If it is the dog’s first transfusion the red cells transfused will have a shortened life due to the formation of alloantibodies to the cells themselves and the animal will forever be sensitized to DEA1.1 positive blood. If it is a second such transfusion, life-threatening conditions will follow within hours.

In other words, the immune system of DEA1.1 negative dogs recognizes DEA1.1 as a foreign substance and so attacks it. This can lead to severe transfusion reactions if a DEA1.1 negative dog is given blood from a DEA1.1 positive donor.

Just like in most illnesses, the immune system takes longer to react the first time it encounters something and so there is unlikely to be an immediate problem if a dog receives a mismatched blood transfusion the first time.

In addition, these alloantibodies will be present in a female dog’s colostrum and adversely affect the health of DEA1.1 negative puppies.

DEA4 and DEA6 appear on the red blood cells of about 98% of dogs. Dogs with only DEA4 or DEA6 can thus serve as blood donors for the majority of the canine population.

4 Kinds Vegetables are Poisonous to Dogs

Vegetables can provide a variety of nutrients such as vitamins and minerals that the body needs, so do dogs need to eat vegetables? In fact, dogs can also eat vegetables, but not all vegetables are suitable for dogs to eat. Here are 4 kinds of vegetables which are poisonous to dogs.


Onions are excitant foods which your dogs could not eat them, or they will stimulate the dog’s gastrointestinal tract, and in severe cases onions can even cause inflammation or infection in the sense of smell of the dog. Feeding dogs with a small amount of onion for a long-term will make them appear chronic poisoning. If you are still feeding dog with onions, we suggest you stop this behavior immediately. Don’t let your love become hurt.


Tomatoes contain high levels of vitamin C, vitamin B1, malic acid, citric acid and other nutrients, which are all good for humans health. However, the dog can not eat a lot of tomatoes, you’d better not feed them to dogs. If dogs eat too much tomatoes, it can lead to dog diarrhea, drowsiness, drooling and other conditions. So it is best not to feed tomatoes to dogs.


Mushrooms sold on the market are harmless to dogs, but they are hard to be digested by dogs. However, to prevent dogs from developing the habit of eating mushrooms, it is best not to feed them to dogs, so as to avoid accidental food poisoning of dogs by eating poisonous mushroom outside.


Potatoes must not be eaten raw by dogs, because the solanine in raw potatoes is toxic to dogs. Eating too much raw potatoes will be toxic to dogs and even cause shock. While boiled potatoes can feed to the dog, because the cooked potatoes have already broken down the solanine. It is best not to feed potatoes to dogs every day but at intervals.

Notices of dogs diet:

In addition to paying attention to the fact that dogs cannot eat vegetables, we should also notice the staple food problems. Do not allow dogs to eat leftovers, or that will lead to dog hair loss and tear stains. Dog food is still the best choice which nutrition contained is relatively balanced.

What will Beautify the Hair of Cocker Spaniel?

Every dog-parent want their dog to have healthy and beautiful hair. For a Cocker Spaniel, its beauty depend more directly on the texture and luster of the hair. So how can a Cocker have beautiful hair?

The study found that for healthy hair growth, dogs need to be supplemented with enough protein, vitamins, minerals, and water every day. Based on this condition, we also have a general idea of which foods are more effective for Cocker Spaniels’ hair growth.

In daily life, we can choose professional dog food to feed Cocker Spaniels. At the same time can also prepare some fresh cooked lean meat, eggs, fresh vegetables and other foods. Comprehensive and balanced diet provide adequate nutrition and energy to ensure good hair quality.

In addition, some dog-parents will buy some seaweed powder or other products which can beautify hair of Cocker Spaniels. Note that if you want to buy those products, be sure to go to a regular pet store. Strictly follow the standards to feeding will be more conducive to the hair growth of the Cocker Spaniel.

In addition to a healthy and scientific diet, to ensure the beautiful and healthy hair of Cocker Spaniel also need dog-parents taking dogs for proper exercise to promote blood circulation.

Finally, taking a Cocker Spaniel to sunbathe and absorbing more ultraviolet rays is very important for promoting the blood circulation of dogs and the healthy growth of hair.

How to Choose Chews for Dogs?

Giving your dog appropriate things to chew on is good for their teeth and gums, keeps them occupied, and decreases the tendency to chew on things they shouldn’t.

A chew toy is a toy designed to be chewed by animals for purposes of stimulation and relief from boredom. The act of gnawing on a chew toy is meant to be soothing and to assist small animals, like puppies, in event of easing the pain when breaking in their adult teeth as the chewing process releases feel-good chemicals from the brain.

Chew toys are a vital part of a happy, healthy animal’s life. In addition to providing hours of entertainment, they also allow the animal to work out anxiety and boredom by being occupied with chewing a toy. Chew toys also distract small animals from chewing on other “forbidden” items, and they assist in maintaining healthy teeth.

But did you know that some chews you can buy for your pet are actually harmful? Unlike-toys for children, there are no rules or regulations regarding toys or treats for pets. Just because you can buy an item in a store does not mean it’s good for your pet. So what should you watch for and what should you avoid?

Toys with small parts that your dog could swallow or choke on are common. Avoid any toy for dogs or cats that has strings, googly eyes, feathers, or any other part that could come off.

Avoid items that are too hard. Biting down just right on an object that is too hard causes a flake of the tooth to shear off. If the tooth breaks such that the tooth root is exposed, the tooth will be very painful and will subsequently become infected. Because this usually happens to the large back premolar that is difficult to see, your dog may be in pain for many months before you even know there is a problem.

You can give your dog bones to chew on but only if they are not poultry bones. Do not give your dog chicken bones since they are prone to splintering. Splintered bones are a danger since they can puncture our dog’s stomach or intestines and put his life at risk. The safest way is buy chew toys for your dogs.

Beef bones are only safe if they are boiled and softened. Raw meat or bones are not safe for dogs or people. Not only can uncooked bones break teeth but they can also give your dog Salmonella, Toxoplasmosis, E. coli or other food poisoning. Chicken, turkey or other small bones can splinter and cause punctures in the mouth, esophagus or intestines, so there also should never be fed to pets.

Pieces of rope with a knot at each end are popular now. These are a good choice as they are soft and gentle on teeth and gums. Throw them away when they start to unravel. Soft plush toys usually don’t last long, and if the stuffing is swallowed it can cause an intestinal blockage. Take these away as soon as they start to come apart, which in large dogs may be in a matter of minutes.

Whatever toys you choose, use common sense and look for tough, long-lasting and durable choices. If your dog likes what you’ve chosen, he’ll be sure to put it to the test.

A Comparison between German Shepherd and Belgian Malinois

German Shepherds and Belgian Malinois breeds are the elite working dogs, often employed by the military and used by the police for detection, search and rescue and many other important jobs. Multitalented German Shepherd and Malinois take top places among best police dogs.

Even though the German Shepherd still takes the top place in numbers among police dogs in the United States, the Belgian Malinois is not far behind. There are many similarities between these dog breeds. Breed comparison between German Shepherd and Belgian Malinois:

Belgian Malinois vs German Shepherd: Running Speed

Both of German Shepherd and Belgian Malinois top speed are about 30 miles per hour (48 km/h).

Belgian Malinois vs German Shepherd: Lifespan

Belgian Malinois life expectancy is about 10 to 13 years.

German Shepherd life span is shorter and is about 9 to 12 years.

Belgian Malinois vs German Shepherd: Good with kids

German Shepherd is calmer and is a better choice for families with kids. Belgian Malinois dogs can also be good with kids if raised with them. Belgian Malinois is unsuitable for a family that is unable to give him the commitment the dog needs. Belgian Malinois and German shepherds are most suitable for an active owner, who can appreciate the high working drive and high energy level of either of these two working breeds.

The owner of a German Shepherd or Malinois should be able to provide enough mental and physical stimulation and company to the breed of his or her choice. Consider another breed if you are unable to provide either a GSD or Belgian Malinois with enough attention, daily activity and mental stimulation. If you are out at work all day, it is unfair to subject either of these breeds to a life of boredom and solitude.

German Shepherd vs Belgian Malinois: Trainability

Both of German Shepherd and Belgian Malinois are easy to train. Dog trainers that work with both breeds report that Malinois has a very high drive and can work a tad bit longer than a German Shepherd. Well trained Malinois are extremely fast in command execution. While German Shepherds tend to have more focus than Belgian Malinois.

Belgian Malinois vs German Shepherd: Barking level

About the same barking level for both of these breeds. Both, Belgian Malinois and German Shepherd bark when necessary. Keep in mind that if the owner is leaving either dog breed alone frequently and for long periods of time with nothing to do, either breed may start barking out of loneliness to keep themselves busy.

Belgian Malinois compared to German Shepherd: Exercise needs

Belgian Malinois has an overall higher energy level and may need even more time allocated for exercise. German Shepherds are calmer and although both breeds require plenty of daily exercise, Belgian Malinois are more active and may require more exercise per day than German Shepherds.

German Shepherd compared to Malinois: Health problems

German Shepherds are predisposed to following health issues: allergies, epilepsy, hip and joint dysplasia, inflammation of the cornea, lameness, chronic degenerative radiculomyelopathy (gradual loss of use of hind legs), and skin problems. Just like German Shepherds, Belgian Malinois dogs are susceptible to hip malformation (dysplasia) and epilepsy.

Are Fruits Friendly to Teddy?

In daily life, owners always spoil Teddy and want to share everything delicious with Teddy. However, Teddy is greedy in its mouth, and it will eat whatever you give it. When owners eat fruits, they will also feed fruits to Teddy. Here comes the question, are fruits friendly to Teddy?

1. Dogs do not need to eat fruit to supplement Vitamin C.

One big difference between dogs and humans is that dogs can synthesize vitamin C in their body by the meat they eat. So it is not essential to feed fruit to dogs if you just want to supplementing VC for them.

2. The pros and cons of dogs eating fruit.

When dogs are constipated or when their appetite is not good, you can feed them with fruits. Because the cellulose and water in the fruit can enhance the gastrointestinal function, and the cool and sweet taste of the fruit can get up dogs’ appetite. It should be noted that fruits should offer with appropriate but not too much. Offering troppo fruits with high sugar to dog is bad for their health. Too much sugar will also cause diabetes for dogs.

3. What kind of fruit is good for dogs?

Apples, pears, cherries, watermelons, bananas and peaches are all dog-friendly, you can feed a small amount of those fruits to dogs. The digestion of dog’s stomach varies from dog to dog, and if dogs get a diarrhea after eating some specific fruits, well, don’t give it any more.

4. Matters need attention of feeding dogs fruits:

Do not give the dog fruit seeds or kernels: like pomegranates, litchi, apricots, plums, etc., because it is impossible for a dog to chew the seeds or the kernels. However, there are no differences between a litchi seed and a pebble in the dog’s stomach. So fruit seeds or kernels are definitely not feed to dogs.

Why Does Your Dog Gives You “Cold Buttocks”?

The hip nudge has been creating awkward moments for dogs and humans for centuries. Instead of licking your face, dogs prefer to turn around and show you its backside. While you may think it is not into you, this is usually not the case.
Well, it turns out that your dog is into you. It loves you so much, and you’re not just the bee’s knees for it. You’re the dog’s bollocks.

“It’s reasonable to conclude that when a dog is backing their rear end into you, they don’t feel threatened. It shows a sign of safety and comfort that the dog is trusting of that person,” a critical care specialist said.

The dog is essentially telling you he’s not going to attack you when he gives you “cold buttocks” that his mouth and teeth is as far from you as possible.

In fact, like so many interactions with humans, it’s vital to understand the signals a dog giving.

“A dog who is coming at you head first with ears back might be uncomfortable or even aggressive, and that is not a situation where you would want to put your hand out for the dog or make it feel threatened in any way,” the specialist explains. “Recognizing these behavioral cues, especially when children or strangers are involved, can be very beneficial for all dog owners. ”

There may actually be a couple of other reasons for a dog’s rump-first approach.

A veterinary dermatologist said that a dog’s posterior is a massive source of pheromones, which would explain why dogs are so beguiled by each other’s bottoms.

“It’s possible your dog may be trying to claim you with his pheromones by backing into you, they’re leaving their scent on you. They want to be as close to you as possible, some will crawl into your lap if you let them do that. There are a lot of dogs who are just very bonded with their owners.”

Tips to Share with Dog Parents

Giving a healthier ingredients can make a real difference in dogs. Here I want to share some tips with fellow dog parents who really want the best for their puppies.

1.Wash your dog’s food bowl and water bowl regularly.

Owners easily forget about the cleanliness of their dogs’ bowl and even don’t knDog how it can affect their pets’ health. Most of us would never think about using the same bowl for a week straight without washing it but many let their dog’s bowl sit on the floor without thinking twice. This allows bacteria to grow and can cause illness from contaminated dishes from a mild upset stomach to vomiting and diarrhea. Make sure to wash your dog’s bowl daily with dish soap and rinse thoroughly!

2.Beware of meat with accompanying word “meal”.

Meat meal, labeled on dog food ingredient lists such as “chicken meal” and “beef meal,” is a nicer way of saying it is “rendered” meat. This type of labeling is legal, but clearly misleading. Animal by-product include materials such as grease, blood, feathers, and entire carcasses.

3.Steer clear of preservatives.

To extend the shelf life of food allowing it to sit on a store shelf for months, most commercial pet food brands are forced to put a bunch of preservatives in their food. While natural preservatives exist, such as rosemary extract, many artificial preservatives can be toxic to dogs if used over a long period of time.

4.Foods to never feed your dog.

Most people are aware that chocolate is bad for dogs. However, you should also stay clear of onions, grapes and raisins, macadamia nuts, and bones! Bones can break and sliver and can puncture your dog’s intestinal tract or cause them to choke.

5.Home cooking is harder than you think.

Ensuring your dog is well nourished with human-grade does not just mean feed your dog food that you would eat or leftovers from dinner. Because dogs eat the same thing every meal it is extra important that their food is nutritionally balanced. A balanced diet must meet all of dogs essential vitamin, mineral, and amino acid requirements. It is best to either consult a vet and get a specific recipe to follow or choose a food that meets AAFCO requirements.

6.Keep your dog hydrated.

Generally speaking, dogs need between a half and a full ounce of water per pound of body weight each day. if your dog is active or lives in hot climate, maybe more. Fresh, natural food also keeps dogs more hydrated.

Do you know above tips? Are they useful to you? It’s wonderful that if you can share your tips with us.
