LOL well I have that problem with my inlaws and my kids. Especially since my five year old can't tolerate milk proteins. Finally I told her do you want to see his painfully cracked bleeding bottom? Don't give him anything or I'll let him stay with you and you can explain to him why his butt hurts
I've just turned into a plain ole' B*tch, I just tell them NO and let them talk. I see how my mother in law feeds her dog so much she's so fat and can't get around and then wonders why her dogs knees hurt
I told her plainly, because you feed her too much. Poor dog likes it but it's not good for her!
