my lucher is coming on well ferreting, marking, patience, reading the game, but when a rabbit hits the net and hes on it before me he trys to drag it away from me until i get him to let go(which is not easy) he is actually quite well trained, but this and his retrieve are bad.Has any one had this problem around nets and fixed it? i can live with the bad retrieve but not trying to run of with them in a net, he retrieves tennis balls and dummys, jumps, heels without a leed when lampingand, good recall , any ideas on the net grabing
