My fourth dog, and my wife's first pet, is over 12 now. For a Lab/Shepherd/Husky mix, that's OLD. She is still very active. Not in pain. Getting up after sleeping for a while can be hard to get the hips moving, and she needs help jumping up into the car from time to time. But she's still healthy. But she won't be forever. 15 would be amazing. My wife and my dog have a very unique friendship and relationship. They are completely devoted to each other. When my dog dies, my wife will be destroyed. Utterly. I know this, and try to help her come to terms with Layna's aging, but... the fact is, nothing can prepare you for that Day After, when you go to pet the dog and she isn't there. It's gonna suck. So the three of us spend as much time together as possible, right now, while we can. I do not want to look back and think, "I should have _____ more with Layna."
