DH is saying absolutely no, we keep the name. I personally don't see it as an issue if we make it somewhat similar sounding to a dog's ear. I'm just not a huge fan (dog is named Pluto) thought we could go for something with an o sound at the end still, with 2 syllables, plenty of names.
DH thinks it's mean when it's already a new everything for a dog and the least we can do is keep his name.
What do you think?
