Also could you try a long line for a start while out, let it out and then do re call with something more interesting to your dog,....but...I do know how you feel, we had a patterdale cross, his recall was excellent until he decided he found something better to go after, then no way would he come back, he was castrated young too so not after the ladies, we were on a farm for the first few months living up here in Scotland and I actualy took raw meat out and gave it to every one, no way did he show any interest at all, we got him eventualy by me talking all excited and running away from him, another time I lay down by a ark pond so he came back to check how I was!!! can you not get something that looks like live bate, eg, a rabbit skin, a dead pheasant or similar? I am not familiar with many breeds as I have labs and they would drop anything for any treat, I often get the opposite problem, if mine know I have nice treats they stay too near to me
