We highly recommend Howard and Marlene Marks! We called them after our almost-2-year-old French Bulldog, Mason, started barking when we left him alone. We live in a condo building in the city, so neighbors were complaining, and we knew we had to do something -- but we needed help! Howard and Marlene came to our home and met Mason, and from their first visit started to teach us how to work with Mason in a way that established our authority and made him feel more confident. With each visit, we learned more technique, and Mason's demeanor and behavior started to change. We still have more work to do, but we're happy to report that our neighbors no longer hate us, and Mason is quite content when we leave him alone. That's right -- no more barking!! Our main goal achieved, we are also seeing many side benefits, e.g., Mason is learning to listen better overall, he's a better walker, and now has great door manners ... and we are learning so much as well! Call Howard and Marlene if you need help! It's worth every penny and they are very kind, patient, and great people who genuinely want to see you succeed!
