Aggresiveness doesn't usually go in breeds. (as pit bull banners fail to apprehend ) It goes by how well the dog was sociallised as a pup. I've got a greyhound X, a dog usually listed as good with other dogs, and she is aggresive with all female dogs. When on leash. If your dog is aggresive on leash, it might just be defencive. If you let her off leash she would be better. When she is on leash, she cannot run away if she gets scared. My dog is fine if both dogs are off leash. You should meet in a tennis court (fenced in ) and let your dog and another off-leash to socilaise her. This helped Jens socialsation.

Heck, she might be scared of other dogs. If you haven't had her since she was a pup, she might have been attacked when she was young. Now she is just protecting herself when she can't rune away.

Good Luck with whatever you do.
