How do you Litter box train puppy?

K follow these steps from the vet...

1. every time you catch him going potty in his litter box give him a treat and say "good boy!" in a high pitched tone.

2.if that does not work when he does go to the bathroom not in the litter box place him in it and don't let him come out till he goes to the bathroom.

3. also another tip is to only have one Word if you would like for him to go potty in the litter box. Such as "go potty" or "bathroom" or "litter box" don't say all of them because he can't catch on .
