My dogs were rescued and already named when I had them so I kept them because I thought they were familiar with them and would make them feel more at home. My little Jack Russell is called Maggie May and my big girl is called Tentie (weird I know) but she seems to like it.
I don't do anything special when it is time for me to give my dog his new name. What I normally do is to look for a name that is going to be very good and exciting for people to remember easily and give it to my dog as his name.
I love picking out meaningful and sweet names for my dog. I'm not among those people that choose random names or unnecessary names that doesn't have meaning for their dogs.
I watch their personality first. Some names sound cool but don’t fit once you see how the dog actually acts. When one clicks naturally and feels right when you say it out loud, that’s usually the one.
