Hey Doc... Ever since we brought this lovable ole weener snatcher into our home, my little yorkie has been losing weight. I'm a little afraid she is getting too skinny. The weener snatcher literally will suck your corndog off the stick if you blink an eye! She also intimidates the little dog around the food bowl. Sweetie (yorkie) will grab her a bite and run. Coda doesn't growl or anything, just nudges herself between anything that gets near the food bowl. I have tried feeding them separately, but sweety eats small amounts all day long. Never will she eat more than a bite or two at a time. Hog gobbler licks the bowl clean and has gained at least ten pounds since coming here. Sweety isn't acting sick or anything, just getting skinny. Her largest has been 5 1/2 pounds. She is down to under 5 now. What to do?
