Any suggestions on a house marker, other than the obvious?

In a crate
water schedule
correction
100 percent on drag line in house
No unattended
No Lifting or marking on walk (squats only)
He is neutered
One and a half year old rescue mutt.

any other suggestions?

Consistancy and time?

Have no problem with that. Actually, I really like that part, because in the end you really have a sense of accomplishment. I am training his obedience at the moment so I can put him on "Place" out of the crate, but I just want to make sure that I am not missing anything. I have not had a marking incident in my house (although I have seen him attempt to when he was tethered to me, so I gave him a correction) but the girl I adopted him from had a huge problem. She was young and had NO CLUE about proper Housebreaking, so I am picking up the pieces. He is a great dog, just this one glitch.

If anyone has had any success in correcting marking personally, I would love to hear about it.

Thanks guys!

I have only had two dogs that ever marked. Both times it was like you are, doing everything right and just at my wits' end. With the first dog it was when I had JUST FINISHED cleaning the leg of the couch for the 3rd time that DAY and he did it again, heaven and earth rained down on him. I flipped. I think I did everything short of kill him. It was a very uh, how shall we say, "unstructured" correction... But it worked. He didn't do it again even once. Our relationship was also none the worse for wear, by the way.

The second dog did it once as an adolescent, received the same (though much less heat-of-the-moment and much more structured) correction, and it worked.

Ordinarily I don't correct housebreaking issues. I do the drag line with pups, teach them where to go, but treat marking as less of a housebreaking issue and more of a direct challenge to authority. I don't believe my dogs (or your dog) marked because they couldn't hold it, or they didn't know where to go, you know?

Hope this helps.

NB: I don't advocate flipping on a dog, but I tell you, my first marker was THISCLOSE to losing his house. I wasn't going to spend 10 to 12 years cleaning piss off the couch leg. I think that he'd agree (from his warm, safe, cosy bed in the living room) that the one complete total flip-out was worth it.

Are you cleaning up with a product that eliminates animal odor? Fabreeze and other products like it are good enough for our noses, but not for dogs. I also heard they contain ammonia which actually cause the dog to continue to mark.
