Hi everyone! I adopted a I believe 2-3 month old puppy back in January and his name is jasper. He is a super mutt and is so absolutely sweet. We got him because I wanted my older dog willow to have a brother and they get along so well which I’m so happy about, but willow seems to be the only dog that jasper gets along with. Any time he meets a new dog he snaps and snarls and growls at them, he doesn’t lunge or actually try to start a fight but I’m so scared that one day he will. I don’t think it’s a dominance thing I rather think it’s that he may be scared. I will also note that I’ve read that sometimes puppy’s have a scary experience and then it’s pretty much trauma after that? I had introduced him to my friends dog who is so sweet but crazy hyper and just wanted to meet jasper but this resulted in jasper snarling and growling at him which I had never seen him do ( he was 3 months) he now still does the same thing to her dog so we keep them apart. I would also like to add that a part to why I think willow and jasper get along so well is that I introduced them on a walk while my mom had willow on a leash and I had jasper and then we walked home together. When he met my friends dog I had let him off the leash in her front yard that is gated and that is when her dog proceeded to run up to jasper. Could this have triggered that fear response? I’m sorry this was so long I just wanted to be thorough. Can anyone help?
