I truly do appreciate your concern for my dogs, but I'm not getting a boxer. They are too high energy for my mom. Secondly, I will not be getting a puppy. 1 year and under. Teaching your dog how to wear a muzzle is actually a great idea. If another dog is aggressive, even the sweetest of dogs will defend themselves, and then you have a law suit. My mental and physical health is in danger, this dog will be an ESA for me, so there's really no choice. Skittles is not aggressive, just scared. She gets nervous around dogs, which is something we need to work on in the first place. I am fully aware of how to raise and train dogs, I apologize if I came off differently. The post was not asking for you to tell me not to get a dog, it was asking for advice on introducing dogs. After some more research and asking my friend (who has 7 dogs and fosters) I have a plan. If anyone wants to give me some advice on introducing them, that would be welcome, otherwise, please keep your thoughts to yourself. Thank you again for your concern.
