And here comes lesson 4 for those who are still keeping up, meaning that you're already running full low DW with a jump or a tunnel after it. For those who are not there yet - don't even try it, keep sending videos of whereever you are and watch videos of others to get a good picture of what this lesson is about and you can work on it later on.
1. Start moving the jump after which the dog is getting his toy A LITTLE in different directions: left and right, rotating it somewhat etc. If it makes the dog fail, set it back to help the dog succeed and then move it again by really VERY little tiny bit. It's better to move it a little every two tries as to move it a lot every two sessions! Keep rewarding by throwing a toy after the contact is done, over the jump. Try to sometimes use a tunnel instead of a jump too. Go through all the possible positions of the jump that still allow the dog to get the jump without collection on a dog-walk. When the dog is fine with that, try adding more jumps around so that there are more possible options. Try running into nothing (no obstacles ahead) too. You want to address all possible course situations other than real turns - we'll get there in the next session.
2. Time to start with an A-frame too! - For all who are already doing the whole DW on at least half height.
Put the A-frame somewhat lower (1,5m maybe) and try running the dog over. I recommend less speedy approach first (starting close to the base of an A-frame) as dogs who were trained to RUN over planks tend to run up so fast they then fly over the top so much that it's not unusual they only land on the floor... If you see your dog doesn't have such tendencies, add more&more speed to the approach AND make it steeper and steeper, I usually go to full height in one session.
Don't worry if not all contacts are perfect at first, they will probably need to experiment some at first. They often first go for one stride but then change to two as it's more comfortable striding for them - or sometimes medium dogs start with two that are too short to get in but then start to extend more and are nicely in with two. Many long-strided dogs will go for one, Bi is always doing one and used to sometimes be somewhat high, but is now always nicely in, even on not so speedy approaches. Bu will normally do two, but sometimes also does one and interestingly, is always in even when she goes for one. Le does two and is sometimes somewhat high as she once flew over the top so much that she crashed to the floor really badly and is now somewhat too careful at the top - but getting in nicer with time and experience.
The thing that I said for running contacts: that the good thing is that they only get better, even if you don't do anything about it... - It's especially true for A-frame. I simply put it in sequences at the second session and they just get better&better. The only problem we ever had with A-frames was with "limit" dogs who were too far with one/two strides that they could make another one, but too high to be in with that one/two strides. You do need to do some more sessions on just A-frame with those dogs and select for good ones. Experiment a little with what gives you best hits as far as handler position and timing of a thrown ball (in advance vs. after the contact) and use that for a start.
With a good hit, I mean anything clearly in. You do NOT want them to generalize DW style too good as you do NOT want them too deep, it's physically too hard on them and they might prefer to not do it if you ask them to come too deep - remember, the easier behaviour is for them, the easier it is for you to maintain it. You are again looking for hind feet separation and you don't want it any deeper as that:
3. Tricks: let's do some pivoting again, this time so that you position yourself next to the target and only click for coming all the way to your leg, touching it. Then either move away and have them follow you or have them pivot back to the other leg. Once they understand the leg is their new object to target, switch to a flat target and then fade it. We need them to know to come to both legs without the target for the next trick.
The other trick we need till next time, for being able to introduce turns, is going tightly around a pole, cik&cap. Shape the dog to wrap the pole/table leg/whatever tightly and put it on a verbal cue.
