Dogs and cats have somewhat different living habits, which is one of the reasons why they have different hygiene habits. First of all, dogs are social animals and like to run around outside, climb mountains and rivers, play, etc., which makes it difficult for them to keep their bodies clean. In addition, dogs’ tongues do not have the same strong cleaning ability as cats and cannot remove dirt and bacteria from their bodies very well. In contrast, cats are very clean animals and they spend a lot of time washing their fur. This not only keeps their bodies clean and hygienic, but also helps maintain the health and comfort of their skin. In addition, there are many small spines on the cat's tongue, which can clean the hair well, and can also remove hair and other debris from the body by swallowing the hair balls.
In short, the hygiene habits of dogs and cats are different, which is related to their lifestyles and body structures. However, both dogs and cats need their owners to bathe and clean them regularly to keep them healthy and hygienic.
