Tosa Inu Breed Daily Care

TOSA INU should be bathed in a tub or shower because no dog likes to stand in dirty water, but they usually like to massage with it. Water temperature should be appropriate, remember to use cold water or too hot who bath, the dog will not like. After shampooing the dog, we apply conditioner and rinse thoroughly. The dog’s fur has a layer of mucous membrane which makes it easy to get dirt on it. Rinse off with a towel to dry the dog as much water as possible, then blow-dry the dog’s hair with a cool air dryer. Don’t let it out until it dries out, or it may get dusty or catch a cold. When the hair is dry, brush it again. After a dog bath, we should use insect repellent, spray on the dog’s skin, according to the specific dosage of the dog’s weight, before use we can look at the instructions or consult a veterinarian.


Because Tosa is so big, it naturally requires more energy, and if it is not fed properly, it often suffers from a partial eclipse. The variety of dog food on the market is rich and full of nutrition. We can even buy fresh food and make it ourselves, which can absolutely meet its needs for food and nutrition.

Fully dried dog food is well balanced and easy to store in bulk. However, as it contains more than four times as many calories as canned food, we must pay attention to portion control when feeding dogs, we must remember not to overfeed.


Tosa Inus, like humans, are born without teeth in their mouths. It is not until three to five weeks that small, sharp temporary teeth emerge from the puppy’s gums. In the fourth month, the permanent teeth that accompany a dog’s life will appear. But because permanent teeth in the growth process, will push the root of temporary teeth, so that gingival inflammation and swelling of the situation. Although the signs of teething vary, every puppy will often fidget, reject the food, drool, and even vomit. Many puppies also show signs of biting hard objects. The purpose of this action is to cause temporary tooth loss and to stop the pain caused by the crushing of the gums. So owners don’t have to worry too much about what happens when a puppy changes its teeth. If their owners do not pay attention to the oral hygiene of their dogs, they will easily suffer from some serious dental diseases. For example, periodontal disease, gingival inflammation, and so on, can cause damage to the bone and tissue around their teeth, resulting in tooth loss. The problem of dog teeth, unchanged, if not remove plaque, saliva minerals will make plaque into dental calculus. Dental Calculus is a breeding ground for bacteria, which can cause inflammation of the gums, and bacteria can even get into a dog’s bloodstream, causing various organ problems. Therefore, as long as the owner pays more attention to the dog’s oral hygiene, many problems in the future can be avoided.

We train TOSA INU to make sure there is enough room in the house for Tosa to enjoy activities, walks, and runs. He doesn’t like to be tied up in the Kennel and prefers to stay with his master. Tosa dogs sometimes bark at strange objects and sounds. So it’s best to reinforce your fence or fence, because Tosa INU doesn’t like other dogs, so it’s best not to let them see you. Owners should be patient enough to train Tosa INU, because Tosa is a slow-growing dog, unlike other breeds, so don’t worry.
