It's great to hear he is feeling much better. I figured his mouth must have hurt terribly. You may have, also, stopped a cancer that was going to form by having his neuter done now, too. It's hard to get them fit perfectly well until you've been buying for them awhile. I hope to have time to sew again someday. It's fun, because they look so cute in clothes. If you get confident about it, you could make him a four-legged fleece outfit to keep him warm, too. It sounds like he's so much more relaxed now that he has no pain. Enjoy that great lil yorkie. He sounds like a sweetheart. Keep the updates coming!
