There are several medical issues that can interfere with potty training. Dogs with a urinary tract infection (UTI) will urinate frequently in small amounts, and will not have much control. You may also notice excessive licking of their genital region. If you notice a change in the consistency of their stool, the cause could be a gastrointestinal issue. Some common causes in puppies are intestinal parasites, having eaten something not in their normal diet, or a sudden food change. If a food change is necessary, do it gradually over 5 to 7 days. If you suspect any of these issues could be a problem, you should consult with your veterinarian.
One of the biggest predictors of a speedy potty training process is owner diligence. If you’re on top of your puppy’s schedule and you stick to a strict prevention and supervision regiment, you should be well on your way to potty training success within a few months. You can consider your puppy almost fully housetrained when you’ve gone an entire month without a single accident, but keep in mind that potty training is an inexact science. It’s best to have several dry months before you can really trust that your puppy understands the rules.
There are a lot of different ways to train your dog. You may choose to sign up for a dog training class, hire a professional dog trainer for private lessons, or even send your dog to board with a trainer. However, plenty of people successfully train their dogs on their own. It's a great way to save money on training costs, and a wonderful way to bond with your dog.
The process is the exactly same for older dogs as it is for puppies; prevent accidents from happening by using baby gates and a crate if possible, create a predictable schedule, learn to recognize your dog’s potty signals, accompany your dog outside and immediately reward for all outdoor elimination, properly clean any accidents and supervise your dog until you’re sure that he understands the rules.
