Fox Terriers are incredibly fun, playful pups who love to play and entertain their human family. While Fox Terriers are highly intelligent, some are more willing to learn than others. While you are housebreaking your terrier, you need to be aware that his strong sense of independence can make potty training him more challenging than many other breeds. Does this mean you can't potty train him? Certainly not, but what it does mean is that it might take longer, and you will need to exercise a great deal of patience. Take your time and use lots of positive reinforcement and treats to get the job done.
The task at hand is simple (or at least it should be): to train your pup that the only place he is allowed to go potty is out in the yard, preferably in a specific area. The problem is that terriers do not like commands and love to mark their territory. Because of this, you need to fence in your yard or you will always have to put your pup on a leash to take him outside. The fence needs to be tall enough to keep him from jumping over it and firmly secured at the bottom or your pup will try to escape constantly. Be patient and keep working with him and in time he will learn to do as he is asked. The training methods are similar to those used for most other dogs, you just have to work on them a little harder and longer to get the job done.
You can start potty training your Fox Terrier as soon as you bring him home--once he reaches 8 weeks old, your pup is ready to learn. Given the fact these pups are very stubborn and often harder to teach, the earlier you get started, the easier it will be to train him. You should choose your cue words before you get started. Keep it simple; use something like "Let's go outside" or "Let's go potty". The simpler you make it, the easier it will be for him to learn it and associate the cue with the action. You will also need a crate for when you cannot watch your pup, treats to use as rewards, and a leash to take him outside on.
