Weimaraners are highly intelligent dogs who were originally bred as hunting dogs in Germany. They learn fast and thrive on positive reinforcement training methods. Treats make a great way to potty train your pup as it will help him to associate the reward and praise you give him with the reason you are doing so. Weimaraners need a lot of exercise and tend to be a bit on the stubborn side, so you will need plenty of patience to reach your goal. Until you are sure your pup is fully trained, you should always keep a very close eye on him or put him in a crate.
The last thing you want is a full grown Weimaraner who still thinks your house is his bathroom. Yet, if you don't take the time to train him from the start, you can expect nothing less. The younger your pup is, the easier it will be to train him. While you can train an older dog, it will take a lot more work. Keep In mind you need to choose a spot in your yard that will become his "bathroom" and stick with it. You also need to be very patient and ready to work with your pup for several months before he will have completely mastered the fine art of going potty outside.
