Does anybody else have a dog that suffers/suffered from this problem?

Can anyone explain why a dog might be specifically aggressive towards males who have not been castrated?

Does anyone have any tips or suggestions for how to train a dog not to be aggressive towards these Males?

The dog in question is a two year old Staffordshire Bull Terrier cross (likely to have been crossed with a German Shepherd)

Thanks for any advice you guys can give

Hi Bow_Wow,

how old were your dog when you got it?
Were you in a puppy play group?

Since when does your dog show the aggression towards other male dogs?

What happened exactly? Is its behaviour generally shown or only when on the leash?

Tell something more about the situation when it acts aggressiv.

In resolving a behavior problem, determine first what could be the possible cause for his attitude. Maybe your dog is not yet comfortable in presence of male dogs. or it could be that your dog is threatened of his own kind.
