I feel your pain. The big guy in the first post just got a tumor removed from his hind quarters for the second time. He hates the vet so much I liberated a surgical staple remover from work and did it myself instead.
Yeah, I know they don't look like Rotty's but they are. The reason I know this is because my wife said that "we" needed to have dogs again after losing our long time Boxers. So, I said "sure as long as they're Rotty's (I'm an old K9 Handler and love Rotty's)".
So, when she came home, she said these are VERY RARE Rotty's, the black one is a French Rottweiler and the blonde one is an Albino Rottweiler.
I know the black one is a French Rottweiler because every time she gets near a German Shepard she plays dead.
