Hello Louise, I just want to give you an update on Mocha. He just turned 10 on Sept 25th. He is in excellent health and has no health problems. He is a huge part of our family and loved by all that meet him. Mocha is a slim 83lbs, which is good for a dog his height. We still walk at least 10km /day, which is usually along the shore of Lake Ontario. People just love his colour and how big and gentle he is.
