We have an 18 month old Rodesion ridgeback and Bull mastive cross, we got him second hand from people who had him cooped up in an apartment. There are many issues we have tried to correct over the past months to some success. My brother moved in with his two poodles and the ridgeback is a dam bully to them both as well towards humans. The dog will be doing fine and then its like someone flipped a switch and the dog starts circling, barking, biting and sometimes she will run across the yard and jump and slam right into one of us. She is pretty good for the most part with the 2 smaller dogs but likes to snap at them when they walk by. That behavior I have tried to stop but she still continues. The other problem is the bones and toys, anyone or dog touches them and she bites and snaps until she get it back, even if she has her own bone she has to have them all. Any suggestion would be a great help, Thanks
