I have a rescue boy....I have had him about a year and a half. When I first got him he did snap and growl some....but we work with him and he stopped. He even tried to bite the vet the first time I took him in! Now a year and a half later he growled at me when I was trying to move his head because he was snoring. I understand I may have startled him but this is something I do ofter. He snores....he tucks his head down under his front feet and snores. I told him "no" and put him out of the room for a few minutes. I think over all he is a little grouchy....I am having his thyroid checked. What should I do next time. I can tell he was abused before I got him. Other than that he is a great boy but I don't want to be growled at.
