How do I get my border collie to stop growling at bigger dogs
She's 2, And grew up with a springer (who died not so longer) And she would always contest with him for food, I always told her off but it seems as ive taken for walks that Smaller dogs she doesn't nip at them, she just looks down on them while bigger dogs she'll run around taking nips as she runs past
I've managed over the months to get him to come to me on command but she always spots them out and if i dont react fast enough she'll run
If your dog is aggressive you should keep it on a leash and/or muzzle it when there is a possibility to be around other dogs
Work with a professional trainer, I can tell from the tone of your post you won't be able to accomplish this without help.
