Dasher is a gem! He's the sweetest dog. How anyone ever gave him up is beyond me. I couldn't have made a better match if I had to. He's a velcro dog, too. Follows me everywhere. Even waited at the sliding glass door while I was outside. He plays like a puppy. I'm worried about keeping him calm after his second treatment. He pants a lot. Could that be because of the heartworms? He sits for treats without being told. Thanks to him, Christmas will be more than bearable. He's such a good dog.
