I suggest you go to the dog farm to buy it ~ When you go to the dog farm to buy it, let the residents show the pedigree of the dog and the parents' information of the puppy to see if the dog vaccination has been completely finished. If some dogs fight at different times, they can go to the pet hospital for injections. If you are a student, you should pay attention to raising dogs ~ you should allocate the time to study and take care of dogs ~ if the dog problem affects your studies, it will be bad. Please think about it!
