I'm considering getting a big dog for my family, but I'm worried about their life expectancy as I've heard that larger breeds typically have shorter lifespans. I've been doing some research and came across the Irish wolfhound and Great Dane breeds, which I really like. However, I'm wondering if crossing one of these breeds with a smaller big dog breed like a Doberman would increase the chances of the dog living longer.
I want to make sure that the dog I choose will be with our family for as long as possible, so any insights or recommendations would be greatly appreciated. Thanks in advance!
