Sent my my 1 1/2 year old pups, Great Dane and Doberman to stay w Derek for a few nights. I love my dogs, but they were impossible to walk and did not have very good manners with company( jumping and barking). They returned completely different. Much calmer and it's a breeze to walk them, even with the distraction of other people outside, some with dogs as well. I 100% recommend this company.
