The results were immediate

I watched your instructional video about the prong collar. I was having difficulty walking my large white german shepherd. I walk with a cane so I am a bit slow for her and I get a bit nervous when she was pulling me that I might fall. Anyway, I bought the collar, put it on as you instructed and started on our walk. The results were immediate with just the flick of my wrist to correct her twice. We just got back and that was the most enjoyable walk I have ever had. She was excellent. Thank-You so much.
