I believe a happy dog is one that gets a good workout as well as the love and care that she/he deserves. Many behavioral issues are rooted in the frustration of pent up energy/ aggression. So a strong play/ workout session, goes a very long way. I can handle any Dog size and believe that no dog wants to be aggressive in nature. Once your best friend and I get aquanted and set on a good schedule, an owner will start to see major changes in discipline and happiness level within their best friends lives, which means an easier life for those owners who may not always have the chance to play and enjoy time with their cherished family member. I can’t wait to work with your best buddie!
