A couple of weeks ago when Higgins had his baby teeth out, I asked the vet techs if he cried alot in his cage. They said that they are so busy with all their patients and that Higgins could see everything going on and was soooooo interested in everything that he didn't cry or bark at all! She said most of the dogs react with interest and aren't as unhappy as we think they are......it was sort of comforting to hear.......
