I'm not really sure, I usually call my dog "dog" and my cat "cat". If I can remember their names I have named them whatever comes to mind. I have had two AKC registered dogs and I named them according to their parents. I had a pure-bred Alaskan Malamute names Yukon Temok after his parents and breed. I also had a papillon named Reeses Pieces. His parents were named after sweet treats. My favorite pet of all time was a Australian Shepard (dog), but no papers and I think it may have been a mix. She was a rescue and I called her "Lady", because she was female.
