thanks mate, yeh this x were very popular in the 70-80s as big deer + fox dogs, they are alot faster than what they look,? they can cover alot of ground with big long strides he should have size+ power when older for (anything) , he got good strong jaw now as pup .Few asked if they guard .well he is 1/2 gsd so you never know do you, but i think you would think twice about coming in the garden with him when he is older .Steve Barton who ive spoke to few times, who had this x in the 70s and still got them now, likes him very much said got a big 1x just like Buck, that will tackle a
