This dog training can drive me crazy. I know that you are suppose to keep your cool, but I certainly didn't listen to that advice this morning. Set-up the large double T that we have run several times before (have actually thought that we needed to move to water swimby because dog has been performing generally without error, but were trying to wait on some rain for the pond). This morning we got up on the wrong side of the bed. I placed the course with the dog in the box...white back pile, all 4 intersection overs had orange or black bumpers. He has done better once I went to off colors on outside to avoid any hooking to outside piles. Well I send dog on back from my side at first intersection, then once or twice as I back up rapidly along base line even gave an over that was near perfect; had to tweet him in a tad to straight sit, this has been common. The problem starts when I get out the 125 yrds or so....no go....move up...no go...nick...up...no go....on&on...Heating him up...as I lose my cool...move all the way to 1 st intersection he goes as directed several times. Start backing up to far back same thing, even try to send from remote and he comes in even with collar in play.....just buries head up my shoes and pants leg. Dog is getting very hot...I'm getting more put out. I thought the dog fully understood a week prior. So here I am thinking where to go from here ...go back to pile work or just back to base line of T backing up slow with pile identified. I felt this morning like I was going to make the word back the worst in his vocabulary and cause some shutdown in association with sending on. NEEDED TO VENT!!!
