Your Weimaraner is a high energy, sporting dog that loves people but can be difficult to train. They have a strong prey drive, and they are not for the faint of heart!
Weimaraners need exercise and lots of it, so leash training your Weimaraner to allow you to provide that exercise is going to be important. The catch is, these high-energy dogs are motivated to chase anything that moves: cats, joggers, bikes, other dogs. Not all of the these passersby will appreciate being chased! You will need to train your Weimaraner to walk on his leash in control, with slack, so as to avoid unpleasant incidents with passersby. Also, you don't want a sore arm from being pulled, or to damage your dog's neck, airway, or spine by constantly having tension on his collar.
Once trained to walk on a leash, your Weimaraner will be a great walking companion who is very devoted and lots of fun to exercise. 'Hope you can keep up!
