Hands up is a fantastic trick that looks great. The dog is taught to sit back and hold both front paws up simultaneously. Easy to reinforce by offering the word hands up and a treat each time the dog manages to get both front paws off the ground. The pure position of this trick makes it look like it was really difficult to teach but if you reward with good timing early on then the dog will perfect his position with little effort from you.
Consistency is crucial. This may mean taking time off work to be there to take the pup outside every 20-30 minutes when they are awake. Crate training will also help the 'penny drop' as it teaches the pup to hold on until taken outside. Then, be sure to stay with the pup in the yard so you are there to reinforce how clever they are when they do go in the right place. Can my dog be a protection dog?
Unfortunately, there is no magic length of time or milestone age when a puppy can be considered fully housetrained and there are many factors that go into how quickly a puppy can be potty trained. Your puppy’s age plays a major role during the initial phase of potty training, as a very young puppy won’t have the muscle control necessary to hold it for long periods of time.
As for the puppy pads, they are only a temporary solution until you can take your dog outside. During the time you’re using them for training, slowly move the pad closer and closer to the door your dog will exit through when it’s time to go out. This will build an association in his mind between that door and going to the bathroom. Eventually, going out that door itself will trigger the behavior in your dog’s mind: “Okay, go.” Can a harness hurt your dog?
