A puppy farmer hoped to make a profit from selling a sick dog which died soon afterwards.
Chloe Robinson sold the pug puppy, called Doug, to an unsuspecting customer for £1,200.
Robinson, of Mansell Road, Kensington, had advertised puppies for sale on two websites and stood to have gained £12,000 in all from her activities.
But the purchaser complained to the charity, Animal Protection Services, after the puppy died within hours of being collected.
The vets were unable to do anything to save the dog, which had to be put to sleep to prevent further pain and suffering.
