I visited a dog obedience class this evening and was quite surprised to see that all the dogs were wearing prong collars. I was able to talk with the instructor and told her my puppy was only 6 months old and weighed 6 pounds and didn't think he would need one. She still recommended one for him in training. I was not really impressed with her style of training nor with most of the information she was giving out. Is this a common practice when training puppies (or adult dogs) to use this type of collar? I could maybe see using one if you had a large breed, stubborn dog, but for a small puppy I'm not too sure. Unfortunatley I live in a small town and she is the only dog trainer in town. She also charges $75.00 for 6 classes which I thought was kinda high. I would try and train on my own but am afraid I'd do something wrong. Training him is very important to me since I take him into the Nursing Home where my mother lives and would like to make it a regular visit for him with the other residents. Any help or advise you could give me with be so appreciated. Thank you so much!!
