How old do you think is just too old to add another dog? If you think so at all. Sometimes I hear of people having a 10-15 year old dog and then adding a puppy and the older dog never really enjoys or likes the puppy. Sometimes I think it's not fair for an older dog, who has lived so long as an only dog, to suddenly have their life disrupted by a puppy. But maybe some older dogs would really enjoy it and appreciate it so I know it just depends on the dog. Jackson will be 3 this October, which I realize is still young, but I kind of feel like I need like a 'deadline' on when to add a second dog. I don't want Jackson to reach a point where he would no longer want a companion. Maybe that's stupid. I know that I will have another in the future at some point. There is no way I could last Jackson's whole lifetime with just him. Not that he's not good enough, he's my perfect dog, really, I'm just such a dog person and I can't imagine living with only one for 15+ years. But his happiness and well-being is also very important to me. So how old was your oldest dog when you added a second? How long did it take for them to like or play with new dog, if they ever did at all? Do you feel it's better to get dogs closer in age? Just random questions.
