My dog has decided he absolutely hates this one other dog in our neighborhood. He is fine to do the meet and greet or walk along with virtually every other dog. But every time he sees this one dog, it's this huge scene - hackles raised, snarling/growling, barking. To the best of my knowledge, he has never even interacted with this dog. The closest they have been is across the street from one another. He has done basic obedience and agility, he is well-socialized, goes to day care with supervised playgroups, comes to the barn and plays with everyone there, and he interacts appropriately with people and all other dogs from yorkie-poos to Great Danes. He does tend to be more reserved - he is not an in-your-pocket dog but likes to check out new situations. He is definitely more submissive in interactions, so for him to have this reaction is really surprising. She is not threatening but she is very energetic and bouncy, which may be bothering him (though he's dealt with other energetic dogs without problems). I don't know the people at all. Do you think I should try to introduce him (safely) to this other dog so he gets over this reaction? Or just avoid this situation because his reaction to this one dog is not being repeated in any other situations? Thanks!
