GoldenPyrs- you're right about the habit forming part. We're already wishing that we'd brought home a boy and a girl.
Ha, ha! I sure understand that feeling! We have our two Pyrs currently and if it weren't for the fact that we just found out that we may need to move, we'd be adopting another. I would so love to add a pup or young dog to our pack!
If you decide to add another to your family, you might consider rescuing a new sibling for Ursa. Though we've had Pyrs since 1989, until 2 yrs ago I seriously had no idea how many Pyrs are homeless in shelters or rescue. Last winter I think that someone here said that there were something like 1200 homeless Pyrs just on Petfinders at that time.
Since we adopted Sammy & Cassie, we'll always have at least one or two rescue Pyr pups in our family at a time. So many sweet pups, so few homes.
Give pretty Ursa a big hug for me, ok?
