That's a sweet-looking little doggie, not familiar w/ the breed(?) Was your last dog the same?
At any rate, it's been 2 years since my dog died and I haven't gotten another yet. I got him only a month or so after the dog before him passed away and he really saved my life at the time. No dog "replaces" another dog, they are each wonderful and unique creatures that you separately become attached to, in my experience.
Enjoy your summer!
