Moose is a Newfie/Great Pyr cross and he's not huge either . he's now 7 1/2 months and is the size of a nicely built Rottie right now. he's filling out , getting wider and his neck is getting big and he's still growing taller, nice and slow. I haven't a clue if he's going to be giant in mind and body or just mind,lol. his personality is all Newf/Great Pyr though, no doubt about it ! He's wonderful, very loving, guards us really well, and is a very independent thinker too, lol.
The pup you are thinking about looks like such a sweet thing, I'd get her in a heartbeat. Thankfully I don't live anywhere near you, LOL LOL
