I have been here before, but the thread seems to have disappeared... Our old doddery dogs find it hard to hold the weight on. They are healthy enough - blood tests reveal no particular problems. Someone here recommended a brand of food, I looked it up, bought some. It has worked very well. I have thrown away the packet and all the information I had about it has vanished into the bin or the ether. AAAAAAaaaaaaaggggghhhhhh!! Can anyone help!!!????
