We take Thor, our 3.5 month old GSD, to Fortunate K9 in Derry, NH. They are fantastic!! We actually started using them about 1.5 years ago, with our rottie mix Kona, who was a rescue with some very serious insecurity/fear issues. With the help of Rick at Fortunate K9 and the work we put in, Kona is a totally different dog now. Julia, Rick, Liz and the whole team at FK9 are fantastic!! They all have dogs who are titled in different dog sports, work as therapy dogs, etc, so they have the knowledge to help you no matter what avenue you want to go down with your dog. They are off of 93 North, exit 4, so not too far from you.
