It’s one of those trained behaviors that’s SUPER simple to teach any dog, but really impresses your friends and family. But more importantly, it gives your dog a way to actually tell you he REALLY needs to go potty. This comes in VERY handy when you don’t happen to be in the same room with your dog when nature calls… but with the ringing of the bell, you can hear your dog asking to go outside from any room in your house!
You can use potty training pads to give a puppy a place to go inside. They are usually scented in order attract dogs to urinate on them. This can be an aid in potty training and may seem necessary depending on your situation. But, it can also cause some problems that may prolong the training period and make it more difficult. Using pads can confuse a puppy into thinking that it is OK to go inside.
The principle behind using a crate for housetraining is that dogs are very clean creatures and don’t like a urine-soaked rug in their living spaces any more than you do. It’s important that the crate is the right size—just large enough for the dog to lie down, stand up, and turn around. If it is too large, the dog will feel that it’s OK to use one corner for elimination and then happily settle down away from the mess. Many crates come with partitions so you can adjust the size as your puppy grows.
So, depending on how old he is and the size of your puppy, it’s unrealistic to expect him to be potty trained before this time. It will be helpful to keep in mind that your puppy is only able to hold their bladder 1 hour for every month old he is. So if your puppy is two months old, they can hold it for about two hours. Don’t go longer than this between bathroom breaks or they’re guaranteed to have an accident.
