I have two 'rescue' dogs and love them both dearly. I second whats been said about the rescue organisations, dogs need homes and both dog and prospective owner are vetted before re-homing is allowed.

The RSPCA do not usually rehome dogs with people who are out at work all day.

If you are looking for a specific type of dog there are 'breed' rescue groups. Eg. Border Collie Rescue. Try Googling for them.

CLINTON ..... Heart Worm is very very very rare in the UK.
