A vet and his assistant have been found guilty of neglect after police found 12 husky dogs living in squalor under a trap door in the cellar of the surgery.
Gary James Cassius Samuel, 49, and Rochelle McEwan, 28, worked at Armley Vets, in Leeds.
Police who were called to the surgery in relation to another matter, contacted the RSPCA after becoming concerned about the condition of the animals there.
In total, 22 dogs and eight cats were rescued by the charity.
One cat, who had collapsed, had to be put to sleep on site, and a dog was put to sleep the following day, in both cases on veterinary advice to end their suffering.
Three further dogs have had to be put to sleep on veterinary advice.
All the dogs were Husky-types, including several puppies, with the exception of two Chinese Crested dogs.
Since being rescued, 21 animals - 15 dogs and 6 cats - have been happily rehomed from RSPCA rehoming centres and branches in County Durham, York, Liverpool, Chester, Leeds and Harrogate.
Both defendants were found guilty of all charges and will be sentenced at a later date.
