we have a bitch we rehomed a couple of months ago, shes so well behaved apart from when shes out being walked-she hates other dogs. My husband says shes been ok a couple of times with other dogs but she has barked aggressively at other dogs whenever ive taken her out. I do anticipate other dogs and walk her away from them but she isn't fooled by that and ofcourse, its not helped by some oblivious dog owners who seem to walk directly towards you, even when the dogs are barking at each other.
I worry she will attack them. Ive never had a dog before, my husband has but im with her more often that he is at the moment.
