I dont know if this is actually aggression, or excited, bad mannered play.
The reason i say this is, this behaviour is almost identical to that of my ancient saluki x....
I got her at 9 years old. She has lived with an elderly collie bitch, and other than that, had never socialised (working dogs dont play, go off lead if not working, get toys etc etc, according to her old owner).....
She plays, by hurtling up to other dogs, growling loudly and pinning them down, letting them up and doing it again, and again and agaiin.
If told to 'sod off' by other dogs (like my dog Rocky does) she will just play chase.
If the other dog submits and lies down she carries on.
It is just a game to her though, not a very nice one, but its a game nonetheless.
As to what you do about it, that i cant tell you. Perhaps set her up with dogs that will say 'sod off' in a good natured way... i dont know.
Muzzling her stops her biting, but tahts all it does, and i suspect she isnt actually biting anyway. She can scare and upset dogs by doing this even muzzled, even if she doesnt bite...
Gah, these sighthounds are sent to try us!
