More than 300 dogs have been seized from a filthy Florida breeding facility, with officers reportedly finding puppies cramped into cages while covered in urine and feces.

At least one dog was found dead and a handful others in critical condition when officers stormed Trish’s All Breed Pet Grooming Monday — authorities describing it as an “emergency operation,” the Tampa Bay Times wrote.

Dogs were in dire condition when rescued, with Animal Control painting a grim picture of conditions inside.

“It was overcrowding, skin issues, eye issues — just filth,” said Roger Mills, Hillsborough County’s Animal Control director, according to Fox 13 News.

“The place isn’t kept up. Animals had urine and feces stains on them. I mean, some of the ones we looked at had hardly any teeth,” he said at a press conference.

The investigation began when people visiting the business to purchase dogs alerted authorities about the disgusting conditions.

Authorities tried several times to talk to owner Robert Royers, 69, but have been unable to track him down.

When conditions didn’t improve, County Judge Daryl Manning put all 350 dogs in the custody of Hillsborough County, who evacuated the canines, the Times reported.

Royers was also barred from owning or breeding another dog ever again.

Scott Trebatoski, director of the Hillsborough County Pet Resources Center, said the center had been shut down after agents found as many as 30 dogs crammed into cages meant for just one of two pups.

Local shelters taking care of the dogs are at capacity. The county is waiving the adoption fees on the dogs but they cannot go to new homes until the investigation is over.

Nearly all of the dogs are small breeds such as poodles, Shih Tzus and terriers.

“We’re asking the public if they can come in and adopt what we have in here, to help make room for what is coming in,” Trebatoski said.
