Ronna, if you do it properly, weaning them off the C/T for heeling will actually INTENSIFY their attention, eagerness and focus. Hard to believe--but very true. What you're talking about is shifting them to a variable schedule of reinforcement, which is more powerful than constant reinforcement. How to start. It sounds like what you've been doing is using the clicker as a keep going signal and the word OK as a conditioned reinforcer (signal that the treats are coming up). I prefer NOT to use a clicker as a keep going signal but YMMV. At any rate, whatever you do, start off by setting up a pattern for them (if you aren't already in a pattern already). For instance, give them a CR and treat at every halt for a few minutes, until they think that they know for a fact that the CR will come at every halt. Then do a halt with nothing--no click, no praise, no CR, no treat. Cold turkey. Give them the cue to heel again and do just two or three steps then give the CR and make the treat a JACKPOT treat. Lots of whatever it is that trips that dog's trigger. Work like this for a couple days--frequent small treats, then a longer period of work, and a bigger treat. What you're trying to develop here is the idea that the longer they go without a treat, the more likely it is that they will get a super-deluxe treat. Then put in an extra halt without a treat. The sequence would go: walk, halt, CR/treat, walk, halt, CR/treat, walk, halt, walk, halt, walk, halt SUPERTREAT. When you see your dog get that anticipatory look when you skip a treat or two, then it's time to start mixing up your treats again. Then bounce around those intervals. Mix it up so that it's not always harder and harder--keep throwing in times when you CR/treat for one halt as well as times you wait for three halts. And then go for four halts in a row. It also helps to be unpredictable as to what your treats are and where they are. Get the food off your body as soon as possible! Put it on a table outside the ring, stash little Tupperwares around the ring, have someone else holding the treats, etc. Using a conditioned reinforcer means that the treat doesn't have to be there immediately--you have time to run across the ring to grab a treat off the table. Sometimes the treats should be relatively boring. Sometimes the treats should be really super-dee-lish-us. Sometimes the dog will do a tiny bit of heeling and get something truly fantastic. Sometimes they'll work a long time and get a ho-hum treat. The key to success is to be as unpredictable as possible. M. Shirley Chong The Well Mannered Dog
