Yes, he was 1/8 GP, 7/8 GSD. It where he got his size. At about 3yrs, he was trim, athletic about 105lbs, When he got older he added another 10-12lbs. And he still thought he was a little puppy and would try and climb up in my lap. He was so heavy!I'm thinking Bear will be close to that size. Didn't you mention once that Joe had some Pyrenees in him?
My pup, Sam, is registered GSD from very good working dog bloodlines. I liked his parents, everything you'd expect. I had working dogs for about 15years. Joe was my first mixed breed and probably the smartest which is saying something compared to my other dogs. They were bred for temperament, drive and intelligence, wonderful dogs. And they are a bit smaller.
Sam is smaller also, will never weight much more than 75lbs. He'd be fat at 80lbs. He's at about 68lbs now and incredibly quick. I wouldn't want to be his target.
Sam's drive is off the charts right now too. It'll be this way a couple more years. By then he'll be wiser, less wasted energy. I posted back when we had about 50 feral cats plaguing several farms here. It took me months to get the situation under control. Joe was no help, he grew up with a kitten and liked them.
With Sam around there will be no feral cat problem in the future. The 3 barn cats here now have to run for their lives several times a day. Sam's keeping order and burning off energy! He learned from Joe who was well adapted to farm life. Sam is already great at alerting me if critters are somewhere they shouldn't be. If they are where they should be he knows to ignore them (except the cats).
Here is "no help" Joe just ignored the cats...
