A survey by the  Pet Food Manufacturers' Association  released March 26 showed that only  10% of pet owners are concerned about their pets' weight , despite one out of three pets in the UK being overweight, according to a  press release  by PFMA.

Petfood manufacturers are sometimes blamed for the problem because of the myth that daily food rations suggested on petfood labels are excessive. In an effort to counter this myth, the PFMA has started an awareness campaign, including a  Pet Size-O-Meter  and  video , on how to assess pets' body condition.

"We urge pet owners to start using our Pet Size-O-Meter and make sure they and their pets have the best chance for a long happy life together," said Michael Bellingham, chief executive of the PFMA.
