If i remember correectly, it was 2 years ago, it was apprximatley 1200 i had to board her there as I live in the north, but it dependas on the type of training I had on and off leash obedience and begining water, he does dp upland but it was of no use to me up here. I have attached a link to his website, but it is a little pricey but when you see the end result it is welll worth it. I take my dog to work so she needed to be calm and listen and it turned out better than expected, and since glen taught me how to keep up training for her I have found using his tips that it is easier to train her to do other things.

Have a look at his web page and give him a call let him know what kind of training you are interested in and he will give you price. A friend of mine gave me his number and he also has a great retriever.
