Calling dogs off

I guess it was an accident, but iv got a bitch i can call off n only thing i can think i did right was, instead of letn her naw on the pig after hobblin or dispatchn, i would leash her n she would pull n pull. I would yank on the leader, snaping it against her neck n yankin her back, yellin at her "here, here, here". It makes it good when im ready to go bc i can call out here, here, here n she'll show back up, usually with a couple other dogs hunting with her. I also didnt hav a trackn system when i first started out n didnt like them gettn to far outa range n would keep pushing on after they headed out n would wait 10-15min n would start calln their names n yelln here. 10-15 later they would straggle in, id wait till we all regrouped n would push on some again. At that time it worked good for my bymyself, but when i started hunted with other that had a system, my dogs wouldnt venture out like their dogs would bc i kept them close to ear shot since im really hard of hearing. It took bout 6mth of workin with her, i got her to were i could call her off, im work on male now, but he is a lil more hard headed.
