Young puppies can’t hold their bowels & bladders for long. If you come home to find that they’ve had an accident in there it’s quite possible that they can’t hold it that long. Generally puppies can hold their bladder for about one hour per month of age. So your 3 month old pup can probably only hold their bladder for about 3 hours. If you’re going to be away at work for long periods of time see if you can get a neighbor, relative or dog sitter to come over to let your pup out during the day.
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.
Many owners appear disappointed that their young puppy will not toilet when out on a walk, yet relieves itself the second it gets back home. This is because the puppy has been taught to toilet only at home (hopefully in its garden), and being creatures of habit, they often wait until they have returned home before evacuating their bladder and/ or bowels.
When you have to leave the puppy alone, you’ll need to confine it to a crate. This will prevent the puppy from peeing and pooping all over your home, and will also help teach it control, since it won’t want to soil the crate. However, young puppies need frequent bathroom breaks, so you’ll also need to ask a friend or pet-sitter to stop by and let the puppy out throughout the day until it’s old enough to go for longer stretches without needing to use the bathroom.
Understand your puppy's particular breed behavior and needs. Research your dogs breed traits and special needs or any behavior that you should be aware of and look out for. For example, If your puppy is a tiny little chihuahua, their bladder will be very small and they will need to urinate more frequently; accidents will happen even if they are well trained.
Success is usually attained in small steps. Training sessions with your dog should last 10 to 15 minutes, two to three times per day. This is especially true for puppies because of their very short attention spans. Longer sessions can cause an adult dog to become bored. Start by teaching basic commands. Try to stick with one action per training session so your dog does not get confused.
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.
