The title on this thread really threw me. My last name is Derbyshire and my dog is really old!
I had a chihuahua that lived to be 22, she might have lived longer if she hadn’t attacked a German shepherd when she was younger.
My sister had a toy poodle that lived to near 20.
Just got confirmation from my sister that her poodle lived until she was 22. Unfortunately she was losing her senses and was found floating in the swimming pool. So who knows how long she could’ve lived.
