Doesnt let sister eat her food!

So Mo lately has been at FOOD HOG!! By all means Missy is a little bit on the chubby side but when it comes to food Mo won't let Missy eat her food. Sometime Mamma has to come out there to gaurd the bowl. He isn't aggressive but playful, talkative side. Missy has a thing for taking her food and bringing it too another area to eat it. She is also a rescue dog. Mo is just a food hogger. Mo also steals things on the counter so the kitchen is like a watchout zone when he comes in there. haha!
