Ive spent a lot of time learning about dogs, how they think, what they want and need. Ive read books on the subject, and have been training dogs my entire life. I am proficient at exercising dogs, especially large energetic dogs who need lot of activity! Whatever exercise needs your dog has, i can provide. Many people will cut walks short, but the reality is some dogs NEED significant distance in order to live a fulfilled, happy life. Adequate excersize is the foundation of having a well behaved dog. I am uniquely suited to this as i am very athletic and can provide a level of activity most cannot. Give me a try, and you will see a rapid and noticeable improvement in your dogs demeanor and behavior.
