I have this little Chihuahua puppy. He always sat around all day. He is five and a half weeks old. He never really walk around, he isn’t active like his sisters. We noticed he got really fat. We thought he had a brain problem. Till I noticed him walking, his walk was very strange. At first I thought it was because he was fat. I then examined him closer. I felt all four of his legs. It’s like he has no muscle on his legs at all! It seems he’s crippled. I compared his sisters legs to his and they have a lot more muscle then he does. He growls, and bites like a regular playful puppy, but he doesn’t move much, when I take him outside, he walks, but not very well. I just wanted to know what this is, and how I can help. I am very worried for him and want to help.
