Get a tapeworm! It worked for Chloe-Fatsoe (my dog). She lost 8.5 lbs. (She needed it too!)
She's okay now. I took her to the vet, and she got some worm killer.
(Just in case there are any morons out there reading this, no I am not actually endorsing getting a tapeworm as a method of weight loss. It's a JOKE!)
