I have a one year old yellow lab and have been following the Chris Atkins videos which include using an ecollar. I have had a hard time using the ecollar since it seems like it works sometimes and then other times it doesn't. At times it works too well and my dog yelps. I have seen the intro videos for Cornerstone Gundog Academy and really liked their method though it is rather expensive but worth it I am sure. I am wondering if changing from an ecollar program to something like Cornerstone when my pup is just over a year old is an option. Also, are there any other options for non ecollar training beyond Cornerstone? Thanks!
