They rarely find new homes because few people know anything about them as potential pets.

Narellan Vale resident Mechelle Sahyoun said she was surprised to learn how suited greyhounds were for life as pets when she first volunteered to be a foster carer for Greyhound Rescue NSW.

Ms Sayhoun volunteered after reading stories of cruelty to greyhounds online.

``I didn't know much about them when I first started fostering them,'' she said.

``But I found they are extremely quiet, they don't bark much at all, they require almost no grooming and they are super affectionate. They are very sweet.''

Ms Sahyoun said the dogs did not need a lot of exercise, contrary to what many people believed.

``I take them 10 minutes around the block every day and they are happy with that,'' she said.

``They don't need a stack of work.''

Ms Sahyoun said she had never looked after a greyhound that was unpleasant or difficult to deal with.

``When I compare them with the two whippets I own, they are 10 times more demanding than the greyhounds,'' she said.

``The greyhounds are always difficult to let go.''

Biddy and Benjamin, Ms Sahyoun's present foster dogs, are both adapting quickly to life as pets.

Biddy is likely to become a permanent resident at her home, but Benjamin is still looking for a new family.

Ms Sahyoun said new foster carers were always welcome.

Donations are welcome too. Greyhound Rescue NSW is run on the private funds of its founders.
