Even if my pets have names... I usually call them by their race, can't wait for the day someone will call me specist (if that is even a word) for calling my dog... dog. Not sure why but it feels easier and as long as I keep the same tonality my dog will react to it.
Alpina perhaps? German car brand (-ish), known for quality. Sounds pretty modern. Fairly hairy dogs, would suit the Alpina/Alpine/snow/winter link. Not too long. Ends with a vowel. Not similar to human names or any commands as far as I know.
