With Insane on this one. My GSD took ages to get the weaves, he was about 4yrs old before he would do them properly. If your dog is large, it's easier to hold the collar than the lead, guide him through & I was taught to say 'through' & 'heel' as he weaved. I also block the exit with my knee. A toy or treat also works well if they will follow it, Zak wasn't that bothered, but Tilly will follow a treat. Most trainers will tell you that it's the hardest bit of equipment to teach. I now shout 'weaveeeeeeeeeeeeeee' in a very excited high pitched voice to get Zak doing them quickly.
