If another dog runs up to your dog with hackles do you take it to mean aggression? I think it does but I have had owners tell me their dog is friendly. Meanwhile my dog is backing away.
Who is right?
(question is because another dog owner's off leash dog runs up to mine and shows dominance by snarling on my dogs back while mine cowers and now she has gone and got another of the same breed. The new one is still a puppy ran but up to my dog with hackles this morning.)
