UGH!!!! I feel your pain. Man I would be livid if my MIL was doing that crap! I told my boyfriend we can't take our dogs over to his mothers house because the dogs aren't fixed and spray all over the house, and she literally gives entire plates piled full of whatever they had for supper down on the floor for each dog. One time it was an entire plate of sweet potatoes with marshmallows, tons of butter, and sugar galore. I grabbed my dogs and made them sit next to me as I stared in disbelief. And if you are wondering, yes just about every one of her dogs has had major surgery, she has SIX.
