The death rate of dogs before vaccination is very high, so the landlord must not take it lightly. As the puppies grow up day by day, the immunity acquired by the bitch gradually weakens, and the fur is short, which makes it very easy to get sick. The nutrition of puppies is also very important. You can make more friends in Bonnet, where many pet friends can exchange dog-raising knowledge with them, and maybe you can find a good in-laws for your dog, hehe.
