This thread is a great example of why it's important to research a breed before you purchase it. Without much research at all you would find that the Weimaraners
"need extensive exercise and training. Its prized for its physical endurance and stamina. No walk is too far, and they appreciate games and play. Weimaraners are high-strung and often wear out their owners, requiring appropriate training to learn how to calm them and to help them learn to control their behavior. Owners need patience and consistent, firm (yet kind) training, as this breed is particularly rambunctious during the first year and a half of its life. This breed is known for having a penchant for stealing food from table and counter tops whenever given the chance. Like many breeds, untrained and unconfined young dogs often create their own fun when left alone, such as chewing house quarters and furniture. Thus, many that are abandoned have behavioural issues as a result of isolation and inferior exercise. It should never be forgotten that the Weimaraner is a hunting dog and therefore has a strong, instinctive prey drive. Weimaraners will sometimes tolerate cats, as long as they are introduced to the cats as puppies, but many will chase and frequently kill almost any small animal that enters their garden or backyard."

Please do research before buying an animial, and don't buy on looks alone. A word of caution: Many research sites leave out the fact that dogs poop, I'm not sure the reason for this oversite. Big dog, big poop. . . . . . little dog, little poop. I know of no breed that cleans it's own poop.
Good luck on finding a good home for your dog, I hope you inform the new owners of the high needs of this dog. It's hard on an animal that has to be rehomed.
