Maltese irritating border collie please help!?

Your border collie is irritating your maltese mix that is why. This is the GS and maltese mix's home and territory and now some young bouncy ****** is invading and jumping around acting foolish. Well that's kind of the way your dogs are seeing it. They will work it out pack order on their own. What you can do is separate the dogs when you play. Think about it if you were a senior you wouldn't want some annoying child jumping around your home. Good luck I have a border collie mix too and they are so hyper! Just make sure to give all of them equal love and attention and taking the border collie out for runs will be helpful.
