Ours is 1 year old and he is fine with our chihuahua and other pitbull, but he FREAKS out at the vet. We have to sit outside with him in the back of the truck until he is called in because he howels and cries every time another dog walks by. He is not aggressive towards other dogs at the vet, mainly because we don’t let him get very much slack on the leash or near other dogs, but he just howels and howels so loud it makes people afraid of him. We try to laugh it off so other people don’t think he is a mean pit, because he is not, but we are getting him fixed soon and hopefully it will help a little.
