Dog Training Advices & Tips

I have a friend who wants to do agility with her dog, one day. The dog, a Border Terrier, is about a year old.

She has some practice equipment and I’ve stressed to her that if she actually wants to compete one day, she needs to make sure she teaches the dog to use the practice equipment right so she won’t have big problems later. (i.e., not running in the tunnel and attacking the sides or running out the entrance.)

She has a tunnel from Ikea, which the dog adores.

She just found a small training ramp at Target, which is what I have the question about. It is built for agility but it’s rather small. It says for dogs up to 150 pounds, but it seems kind of pointless for such big dogs. It’s less than a foot tall and about 4 1/2 feet long.

Any tips on playing with the ramp? Right now it’s all fun but she doesn’t want to develop bad habits for later. Should she make the dog walk slowly so he at least steps on the downramp? As in, imitating contacts?
I ran out of space, but I also wondered, since it was small short both length and height, about making the dog stay on it from the onramp to the offramp. Maybe a wall on one side and something on the other while teaching him?

Anyway, any tips at all that you have about having fun with the equipment while not training bad habits for later agility would be great.

Thanks!
