He's 6 mos old. Has had no formal training, but shows interest in the cows. Maxx has been just riding on the tractor when I feed and watching the cows. This morning he jumped off and went bouncing after the cows. My fall cows with 2wk old calves were NOT impressed with this new "coyote" in their pasture . It turned into a real poo show. He needs to learn to come when called regardless of what's going on around us.
I can well imagin the wreck that transpired but the guilty party is not the dog but you. Its a given that even a youngster with a solid recall will blow you off when he turns on. Be prepared to not let it happen in the first place i.e. contained while on the tractor or anyplace else that might trigger his instinct. If he escapes keep your mouth shut (cardinal rule never give any command that can't be immediately rectified), hunt him down &
praise him when you finally get him caught. Under NO circumstances punish him...you're a day late & dollar short, he won't understand & will quickly associate a recall with punishment. A lot of hunting people use Shock collars. IMLTHO they aren't warranted with stock dogs. If you're not comfortable training a dog to useful status, send him to a skilled trainer.
