Got a jumping bean of a puppy?
Weimaraners don’t like their personal space being invaded. If you sense them starting to jump, take a step towards them, and step into where they have their front feet. Their reflex will be to take a step back. For the chronic jumpers, my foster dogs also carry a short leash around the house with them. When they get excited, I step on the leash in a place where there’s not enough slack for them to jump. And then I reward them for not jumping when they keep all four on the floor. Good luck!
