Animal rights protesters will descend on Forest of Dean District Council to oppose a puppy farm's bid to renew its breeding licence.
The concerns held by Campaign to End Puppy Farming come after a vet's report criticised the conditions in which dogs are kept at Hagloe House Farm, Blakeney.
The farm wants a new permit to rear breeds including pugs, Chihuahuas, poodles and schnauzers, and a hearing will be held tomorrow at 10am.
Campaign founder Linda Goodman said: "An inspection by a vet in February 2013 revealed major shortcomings such that he would not have been prepared to support re-licensing unless major changes were met.
"The premises have been allowed to build numbers to around 90 breeding dogs over recent years with the council failing to set any limit on numbers."
