Lynn Everett, 65, of Eaden Crescent, Hoyland, pleaded guilty to breeding three litters of puppies within a 12-month period without a licence at Sheffield Magistrates Court on July 7.
The court heard that Everett had been a breeder for 20 years, and there were no welfare issues raised with the breeding of the puppies.
However, a change in regulations, which Everett had not made herself aware of, led to the prosecution under the Animal Welfare Act 2006.
Everett was was fined £3,000, and had to pay costs of £938 and a victim surcharge of £181, totalling £4,119.
Julia Burrows, director of public health for Barnsley Council, said: “During the pandemic we have seen a rise in the number of unlicensed dog breeders. Anyone operating a business selling puppies for profit, when this involves the sale of more than two litters of puppies in any 12-month period, must hold a licence with us.
“These licences are important to make sure dog welfare standards are met. This prosecution sends a clear message that any breeders attempting to sell puppies without a licence will face legal action.”
Ms Everett appeared in a Channel Five documentary called 41 Dogs in a 3 Bed Semi in 2015 alongside her husband Tony Morgan. At the time, the pair owned 41 dogs.
