One of my dogs is a real training monster. She loves training and hates the session to be over. Problem is it is getting harder and harder to put her away so I can train one of the others. She simply will not be caught. I have tried taking hold of her collar during the session and the rewarding her and continue the training but she seems to know when I am planning to end the session. I can't always have a lead on her as I practice aglilty and that can't be done on a lead.
Even starting training sessions is problematic as I usually train one of the others first so I don't have the problem of trying to catch her but she literally fight s to get to be trained. If I manage to get one of the others outside to train, when I try to slide through the door without letting her out (small JRT so she can fit through very small gaps)
she will jump up and down at me and squealing and biting. If I can I put her in another room before I start a session but she is very good at picking up the signs.
i have done lots of work at taking hold of her collar and letting go again and also control at doors but it all goes out of the window when I want to do a training session with just one dog. Any suggestions most welcome.

Work her on a line?

you can't train agility on a line. Thanks anyway.

Perhaps rather than training the agility you may need to work on overall control and obedience? ;)

I am thinking I will need to do some sessions just to work on this issue.   her overall obedience is excellent. She is a pleasure to live with. It is just training that turns her in to a total monster.

my trainer starts people off training agility on lead-i was surprised,but you can-even the a frame and weave!

I'm thinking the sessions are at home as opposed to a class (you mentioned putting her in another room)?

Do you have a cue which means the session is over?  I use 'all done' with mine and show them my palms, they then know their session is done with and although I do get sulks, it's a lot easier to swap dogs then.

If one of mine was doing what yours is - and Raine can do sometimes, being part malinois she just wants to go on and on and on and on and on :-P - I would train her last and when the sessions ends, give the cue and just walk away so that she knows it is done, no questions, no chance of an encore.  With a dog like her I'd have to do that a fiar few times before she got the message though and if she were like your girl, I would use a longline like others have suggested and work on basic control exercises in the meantime.

Edit: by which I mean self control exercises, not general obedience - might be worth you having a look at the Control Unleashed books/DVDs (DVDs better from what I've heard, I have the book and it is good but hard to get what she's saying at times).

> my trainer starts people off training agility on lead

Thanks Pam but I am working on more advanced handling techniques so I really need her to be off lead.

> I'm thinking the sessions are at home as opposed to a class (you mentioned putting her in another room)?

yes. I like to do some training at home whether a bit of agility or teaching tricks or obedience. I do sessions with one dog at a time. As soon as she thinks a training session is in the offing she turns into a monster. she will attack the other dogs by the door as I try to separate the one I want and attack me if I am trying to get out without her. If I can I try to get her shut into a cage or separate room before I start so I can train the others first then do her last. Problem is she seems to pick up that I am thinking about training earlier and earlier so I have real trouble getting her shut away. She also makes a huge row squealing with rage while I am training the others.
Last night I tried to train her first hoping that that would make her happy and I could train the others in peace but even though I did sessions where I took hold og her collar and then let her train some more at the end of the session she was off again and wouldn't let me catch her and wouldn't come in out of the garden so I couldn't train the next dog out there.
I waste so much time trying to get the little horror where I want her I could double the training   time if I didn't have to deal with this.
I guess what I need is a training plan so I can tackle this systematically.

if she is food orientated throw some smelly food ie meat on the floor at  your feet when she goes for it if her obedience is good tell her to sit or down then let her take the treat as she does  you get hold of her collar.
One of my beardies was a horror for this at the end of agility because she was so fired up I was told to do this and it worked.

SOunds like she loooves training! How about trying to associate being caught as a positive thing! I don;t know how greedy she is or whether a toy might do the trick but for example - every time she gets caught and put on a lead she gets to play tug or gets treats. I'm sure you already thought of this but whilst you are training her- catch her mainy times, have a 1/2/3 minutes break and start again. Go back inside for 2 minutes and get back out to train again.
It sounds like she's a clever monkey and you'll need all your cunning skills to trick her into letting herself be caught!

no way would I be bullied into a training session by any of my dogs. Love it as she does, bad manners are being rewarded. I'd have a crate ready and start the routine you have before you start training and bad manners result in a time out whilst you train the others. Or make a very very big show when she starts of being digusted and literally slam your treats away again and stalk off. One of mine was like that but not to the point of attacking,but the second he started away went the treats and away went me.So he lost everything that was important.

Training is fun but I'd be working on slowing her down a little before the session starts as she's being rewarded forthrowing her weight around. You wouldn't tolerate a child pushing in front of another so don't indulge her. 

If this were my dog I`d stop the agility till I got her behaving better (no offence meant). I know you and she love it, but even a few weeks spent on regaining control now will actually make it easier to work her in the future.
Maybe you and your trainer could work out a programme of training around the course, with an emphasis on control?
