Eeeeep, do you have the option to just not use one? This is a puppy class they are using them in?
No this isn't a puppy class, it's a basic command class.

Is this the trainer you told us about before? Normally when you do formal training, you don't correct unless you're sure the dog knows it so it doesn't look like Jasper will get many corrections if you start him off right. Here's a tip I stick by when I train my boys because I also use formal training.. give double praise for a correct command after you do a correction (hope that made sense)
Yes thats the trainer, first I thought it was a guy, then I thought it was a girl lol but its a guy, for sure! Jasper probably wont need many corrections, he said the training depends on the dogs personality and size, like he wouldnt give Jasper the same correction as he gave the weimaraner, he helps us get to know our dogs, and then we know how to correct them and which ways they learn best, hes really good, he loves dogs he shows dogs, breeds dogs( ) trains dogs and grooms dogs...
