Fetch practice 3 dogs

As we prepare for a June AKC Fetch trial, I wanted to determine: 1) which dog likes which bumper?, 2) can I throw the bumpers accurately?, and 3) how will the dogs do with a 30 foot toss? The yellow markers are 30 feet from where I'm standing. Each bumper is weighted differently. Jilly had a hard time seeing the bumper. I threw Higg's bumper too far, but he's quite capable of finding it. Well, the training is off to a decent start.
