Hi, this is Victoria Warfel, with DreamDogz Training located in Gainesville, Florida, here to talk about how to stop your dog from being aggressive towards other dogs. If your dog is aggressive towards other dogs, and this could be barking, growling, lunging or any number of things that make it feel like your dog isn't safe to be around other dogs, seek a professional's help. Between the time that you notice this happening and seeking the professional's help, keep your dog away from the other dogs or whatever it is that he doesn't like. And if you have to muzzle him, it's going to be the safest thing for your dog and for any other dogs. But seek a professional's help, is the best advice I can give to you.
