ALMOST a third of Britain's pet owners have an animal with a weight

problem. Astute acting performances can win dogs and cats extra helpings

from the entire family, says the People's Dispensary for Sick Animals.

And food can become too important and a sign of affection where a pet is

an owner's sole companion. Gairn Ross, PDSA director of veterinary

services, said yesterday: ''Between 25 and 35% of British pets are

overweight and suffering various health problems as a result.''
