Why can't we afford a dog at home?

Maybe you didn't take good care of your dog. Keeping a dog at home requires certain professional knowledge, just like raising a child, so that it can grow up healthily. It is suggested that the landlord go to the bookstore to buy some related books or Baidu to search for relevant knowledge, or go to the dog-loving network and dog-loving network to exchange and learn with other dog lovers. I hope the landlord can make the dog healthy, and I wish the landlord can get happiness from the dog.
