Why did my senior dog defecate in the house?
My 10-year-old 75-pound husky/collie mix defecated in the house this morning for the first time ever. He didn't even seem to be aware that it had happened. He's also passing enormous amounts of noisy (and smelly) gas.
He's basically an inside dog, but has access to the yard through his dog door. I walk him twice a day, which is when he usually "poops".
He had a complete physical done two months ago and came away with a clean bill of health (except for a non-cancerous fatty tumor under his front leg). He does have arthritis and the beginning of cataracts, but neither of these explain what on earth caused him to do this. I'm very concerned; Smokey has been my best friend all his life. I hate to think this is something really serious.
