We have a 14 year old dog that we truly love. He was our pseudo child for many years (until last year when our son arrived). Many people have said that when they die, they want to come back as our dog. But lately, he's just not himself. He has cataracts, is mostly deaf, and really can't smell. He's overweight, and tends to sleep all day, unless he's begging loudly for treats, or crying while we are at the dinner table. He has also lost his potty training, and is urinating all over the house. Even when we are there, he will not scratch to get out, or let us know, he will simply pee on the carpet. He is just not the same dog. He does not interact with us much, and hates our son, growling at him, or just simply ignoring him. He doesn't sleep with us, or even sit in the same room. He often seems to be out of it, not knowing which side of a door to go to when I open it, bumping into walls, etc. It's gotten so bad that I find myself always mad at the dog for peeing, or crying at the table, or whining for a treat (he gets plenty of treats, by the way. I figure at 14, what's another Snausage going to hurt). I've been really wrestling whether to have him put to sleep. I can't say he's ill, or in pain. He simply does not have a quality of life anymore, being mostly blind and deaf. I wrestle with it because I wonder if I'm doing it for his benefit or ours. I hate having to clean the carpets, having the smell in the house, and having my son play where the dog has peed. But, I also don't want him to be suffering. What have you guys done?
