I have a 10 year old cocker spaniel. Today she bit my hand when I was trying to get her to go outside (she was refusing..she is a stubborn old girl). I had put my hand under her torso area..but was gentle. We have to muzzle her when she gets groomed, she bit a groomer once...so now I have to spend $100 to have someone come to our home every couple of months. She has always had a tendency to snap, if someone touches her feet...but otherwise is a loving and gentle dog. She is not aggresive. I have kids, she bit my son one time many years ago when he stuck his head in her foodbowl , so I blame that more on him, although he was only 3 or 4..and luckily he wasn't harmed..but it sure scared us. Has anyone had to put a dog down because of biting, she isn't vicious...but I fear that in her old age she might lose all patience with the kids or their friends. What do I do? I LOVE this old dog. She doesn't have a medical issue with her feet, we have explored that...she has just always been sensitive. I have always had cockers...and I know sometimes they can get snappy...but now with kids it is different. Opinions?
