you do it close to start with & gradually go back.
Are you using the dogs name ie "shep back"? because the use of the name can sometimes confuse the dog, & make it think its doing a recall (though i do use a name on soome postions)
What you can do is /lots of ideas
throw a titbit over the dogs head,after every postion so hes constantly moving backward
Put Titbit pot/toy behind the Dog so his reward is coming from behind.
Of he Knows food refusal Put a titbit on the floor about a foot infront of of him & tell him to "leave it" then do the postions
****with thought & care*****dog on a long long long line, attaches to collar & through something on a wall & then back to you , then use a gentle pressure through the postions that hes not coming forward on.****Some dogs do not like a line & youve got to have good timing & a light touch.
With Stays, dont teach them anywhere near the time place you are doing above.
I find it good to return to the dog alot & titbit IN position & then leave again, so the dog is getting lots of postitve reinforcement for staying. In agility youll be able to keep commanding & look at the dog which will help!!!!!
