[YorkieMother]

I have had Black Russain terriers think 75 to 120 pounds up next and playing with both my yorkie and new pup no problem but my dogs are well soicalized and I with them.

I have had them with 120 pound GSD cross and I can leave him with my old girl.
I have had them with 80 nephy border cross and watch more close as he is bouncy.
I have had them up next to a portie with no problem after I educated her on being a little more gentle.
I have had them with a BRT landed himself in time out for grabing my old girl and he never did it again.

So it depends on the dogs and if they get along and I never leave my dogs alone together unless it with the GSD cross he great at dog speak and moves slow.
