How Do I Potty Train My 3 Year Old Pomeranian/chihuahua Mix?

Go to a pet store. Get those little puppy pads for potty training.The way I trained my puppy was by buying lots of dog treats and everytime she used the restroom puppy style outside she would get a treat. Also remember that everytime he/she uses it outside say something like "good girl/boy go potty outside lol. That's what I did and it worked like a charm.

Training a 3 year old puppy is quite difficult. But what you do have to do is keep an eye on the dog at all times.. basically keep some treats handy at all times and when you see the dog sniffing around for somewhere to "go" pick up the dog before it has time to do it.. and bring it outside.. place the dog on the grass and wait.. remain patient, and once it does go, give the dog a treat and reward it by giving it it's favorite toy or simply just playing with it.
Hope this helps.
