The attraction had become popular after social media videos showed customers enjoying play and petting sessions with as many as 30 dogs.
But in May 2024, the experience had its licence revoked by Somerset Council following a police and RSPCA investigation.
This week the magistrates court was told a visit to the site by the RSPCA and Somerset Council found conditions were “grossly overcrowded”, with 20 of the dogs living in a galley kitchen with a concrete floor and others cramped into a bedroom.
This left the retrievers fighting over limited resources.
Somerset Council said it expected St James, of Carhampton in Minehead, to drop an appeal over his operating license now he has been convicted.
The experience website said anyone with a gift voucher should get in touch by e-mail.
