Check with Don H. He is very knowledgeable in dog training. I’m sure he will put a post on shortly. Remember your dog’s handling is a matter of time and perseverance on your part. You cannot rely and it certainly won’t work if you think the collar will be a magic cure. Having said that, I always put it on when I’m in the field. Take a few minutes each day on basic commands and move on when the dog is ready for more commands. My dog is the same way. I took him out last night to work some fields, the first ten minutes he has to run like a mad man, once he gets the initial burst out he is focused. As far as the collar, research what features you think would be helpful and then compare them head to head. My collar is only a year old, but its so muddy and beat up, can’t even remember what brand. Decide if you want a beeper, what range you want, digital display, cost, ability to fine tune the intensity of the shock etc. With range, if it says up to one mile, that it probably isn’t near that strong. Some are only 3/4 of a mile. If I had the cash, I would get a GPS as well. Until the dog handles reliably, if the dog takes off, the GPS could save you a lot of time and heartache in looking for a dog all day. And your hunting buddies won’t be as mad at you. Just my 2 cents.
