I am particularly good with sport breeds... labs, goldens, pits, terriers, etc. I like to walk and run and so do they! I live within walking distance of 2 dog beaches, so swimming is an option. The dog park is a couple of blocks away and i go there a few times per day. I am also very good with walking training and mental exercise. I'll bring a bag of treats and run through all the tricks your dog can handle. Sport breeds need mental and physical exercise or they get bored, have behavioral problems and can be unhappy. Let's get them outside, playing, thinking, swimming, running and being good dogs. If you have a high-energy mutt who needs to work it's muscles - I'm your guy! I own a terrier/lab mix. He's 70 lbs, but he is great with tiny dogs, big dogs, cats, rats and people. The two of us will keep your dog happy and healthy.
