I legitimately was impressed. My Bierstadt (4 month old golden retriever) was everything we love in puppies but hate in dogs - rambunctious, no manners, jumping everywhere, pulling at everything. He took a 3 week board and train course with Complete Canine and came back the most amazingly well behaved pup ever. He still has his puppy ADHD, but he's now following when on the leash instead of pulling, sitting before doors, staying in place. He's so happy to play and be a puppy and he's so much better around other dogs now. I can't say enough about the change in 3 weeks and look forward to more classes and more learning in the near future.
