I haven't been here in a week or so. Thanks so much for that info. I have been giving him Ester-C, which is less harsh on the stomach. I give him all his meds with food, and yes, the weight is starting to be a problem, so I just switched his food to a lower calorie one. I watch the treats too. Thanks for the advice about him going around other dogs...we have one from across the road who is Cosmo's friend, but his owers don't always take the best care of him. Not abuse or anythng, just they let him roam. I will be careful about that. It's really nice of you to take the time to do this for me, and for Cosmo too.image
