Hi...We will be starting Shelly in some type of Pet Obedience Classes as soon as she is old enough. She only 9 weeks now and had her first set of shots so far. I have been told that she needs 2 sets of shots to start in any classes. So in a few weeks after she has had another set of shots she will be starting somewhere. We have been looking into a few training schools in my area and the one I really wanted to to start her in informed me I had to purchase a Pinch Prong Training collar for Shelly. (Now flashing lights are going off in my head. Remember my 9 year old son is going to be training her in the classes.) I told them that they looked horrible and looked like they would cause alot of pain. They asured me everyone uses them and they were not painful collars they just looked that way. They told us they were alot better than a choker chain collar. Has anyone else gone to pet obedience or puppy classes and what type of collar did you use? Any help would be nice. Thanks
