Girls, hello everyone, I have a small dog, my Spitz is Pomeranian, and I'm worried about how he will get along with the child. 1 What worries me is his fur, has anyone had allergies in their children? 2 What worries me is if the dog sometimes gives, how do kids react to it? 3 When the kids start crawling, how do they communicate with animals? Have you had any experience like this? I love the dog very much, she's been with me for three years, she's my companion, always by my side.
