please go to
http://orangedog.forumup.com/index.php?mforum= orangedog and look at "behaviors" and potty training. Also check for medically, get a urinalysis done just in case. If he goes to bed with a full baldder you are correct, he will have to pee and then go again in 1/2 hour then again probably in an hour, if I told you to drink 24 oz. of water in a hour, you would have to go probably in about 1/2 hr maybe less, then you will probably need to go again a short time after that and maybe about an hour after that to get rid of it. If you spray a deternet on the bed to keep him from going there he "might" not lay in his bed at all. It is okay to take up the water at night before you go to bed and take him out to potty right before bed time, if you leave water down for him then you'll have to get up at intervals in the night and take him out. WHAT GOES IN MUST COME OUT. If he has not gone 2 months straight with no accidents he is not Potty trained. I am not sure where you got him from, if from a petstore or backyard/puppymill breeder, dogs live in bad conditions, where mother never taught them to move away from living/sleep area, or they don't get a chance too, (kept in cage or small area) they learn to live in their filth, the "instinct"to move away from the living area is destroyed, so it's harder on us to get them trained to not soil their area. If he has something medical you may have to leave water down at night and get up, till he learns you don't want him going in your home (or crate, a house is just our big crate). Check out the web address I gave you please. And yes...treat then praise him right after he goes where you want him too.
