The first one is that the dog has a very painful memory of this place. Just like all the children of human beings feel very unfavorable, once they enter the hospital, they will become more and more irritable, and this is also available for dogs.
Most dogs have good memory abilities. If they were naughty when they were in a pet store and their owners were not around, the staff of the pet store would not be as patient as their owners. It is very likely that the method of cultural education would be more extreme, so that the dog would think of these pains when they arrived at this place.
The second reason is that dogs don't like dog cages very much. Generally, when you walk into a pet shop, you will have various dog cages. Dogs are a cheerful and active pet, so it is very resistant to this type of particularly restrained iron cage. Especially when it walks into the pet store and sees it full of dog cages, it will inevitably cause a shadow to the dog's mental state, and it is very afraid that it will become a member of the dog cage. Once this kind of conflicting psychological state occurs, it will gradually become larger, which is why it is very disgusted with pet stores.
The third reason is that dogs don’t like to take baths and are very worried about water. It is important to know that in addition to firing fire in the hearts of many small animals, they are afraid of water. This kind of fear engraved in DNA is inevitable when they take a bath. When the measures are not effective, when the pet shop takes a bath, there are a group of strangers around you. You can also have a very noisy hair dryer in the future.
