 the bumper in the water you know 20 yards out 30 yards out something like that real short quick let the dog swim out get it come back and you can really monitor whether that dog's getting hot pretty quickly as opposed to if you're eroding and you're you know you're a mile into it and all of a sudden your dog starts to overheat you know you've got a long way from home it's hard to monitor hard to get them cooled off so um i do like some of the the quick sprint things in the summertime um
