I have a mixed breed - lab x- and when we got to the building he was at the ene of his leash....Totally embarrasing me! They were patient and understood that I was trying to get control. It took a lot of work and effort, but we now are a team, and we BOTH enjoy our walks!
Pros: Cheapest in town, a lot of class selections too
Cons: most classes are night, so for some that might be bad
