How do you know when your turn is up? You are ringside and the dog you're after is in the ring... are you watching or are you working/warming up your dog.
Asha sounds like Ripley in that she would probably do best being brought out before she has a chance to look at her surroundings and lose focus. I sit by myself ringside and watch the other competitors. You'll get an idea how long each run takes, and get a feel for the judge's style this way too. I would say most runs are in the 3 min range but higher levels can take longer. I do the same as Art in pre-entrance ritual. The bait bag goes on the table and last 30 seconds bait is out to get her amped so she knows its waiting for her once we're done.
Maybe practice taking her somewhere completely new and act like the car is her in her crate at a show. Take her out, immediately start warming her up/engaging her... 1-2 min. This needs to look the same as it would in trial. Don't do one thing at home and something different in trial (easier than it sounds, I know). Its a pre-cue that work is about to begin. At ringside for my warmup I
always have Ripley touch my left hand, then right hand, then fall into a by-heel. Do not over work her. Keep it short. Have a goal in mind before arriving, she performs well, have fun playing with her and leave.
Practice building duration of you standing there yet not looking at her, with her at attention, reward. This happens often. The judge gets done with the dog before you then walks to the table to write in their books and the ring stewards start chatting with the judge a bit much.
To keep Ripley's focus while waiting I do hand targets. She sits beside me and I will put my hand above her for her to touch periodically so I know she is still engaged with me. I will reward her at random intervals and I reward from my arm pit. Stick a piece of bait in your left arm pit and open your arm up to drop it straight down to them. This trick really helped keep Rip's attention UP. I also taught her to rest her chin deep into my hand and I'll rub or stroke her muzzle to offer support. This chin rest is usually what I'll do while waiting for the judge, waiting for the steward or whatever... The nose touch is pre-cue that we are about to start the next exercise.
Have two cones that are your "gate". Practice JUST entering this gate with focus for one to two steps. Reward. Build your duration of entering before reward. Now add entering plus setting up (having to heel over to x spot and sit and wait for judge) before rewarding. Again, sometimes judge takes a while from telling you to enter the ring to them standing next to you telling you the intro, "good luck" and "are you ready?"
Practice whatever routine you want to do with "are you ready?" The moment I walk into the ring, I personally never look away from my dog. Judge asks me if I'm ready - I don't look up to the judge. Im smiling down at my dog and say "ready". I trained Ripley at home that "ready" equals head snap up and eye contact. Reward. So whenever the judge says "are you ready" if for some reason Ripley looks away, she hears that and snaps up to look at me. The word ready is used in rally and obedience. Not sure about agility but its probably pretty universal and its super handy to have your dog hear it and know "time to work!"
Do you see the dog exit and wait at the gait for a nod from the judge? 30 seconds or 5 minutes?
Yes, once the other dog exits (I would let them exit before approaching) the judge will call out your number not long after and "come on in. Always wait for the judge. Some competitors choose to sit and wait at the ring entrance... I like to do a fluid motion and start back about 5-10 ft and heel into the ring to continue heeling right to where the first exercise begins. The ring entrance is part of our routine. Plus, the dog leaving is supposed to be under control but at lower levels this is not always the case... don't let it mess up your dog. I'm pretty sure Asha is like Ripley that, if a dog is overly excited leaving and gets in her space, she loses focus.
