The first name that got into my mind when I saw this dog was: Sniffles.
Don't ask me why. It just happened.
More suggestions would be:
Roofie
Crackles,
Charles,
Jack,
Bobby,
Beavis
Pepe.
You should try one of those baby name generators lol, maybe it'll generate an interesting name, who knows. Nice sketch, by the way.

Crac dog perhaps...
