Ms Clark, 59, said the property was completely cut off, with the road flooded “for the 12th time since July”, but added: “The dogs are safe. I kept them alive yesterday.”
She told BBC Radio Wales Breakfast on Wednesday she had tried to bring the 37 dogs living at the sanctuary to safety, as water levels rose rapidly on Tuesday, but “every level we went up, the water followed”.
She said the fire and rescue service helped nine of the dogs to safety using boats, but the others had to be left behind because “some of [them] are really reactive, and can’t share or go elsewhere”.
“The rest are just in crates up in the loft – where they’ve got nowhere to go for their toilet, or any food left,” she told the BBC.
“It’s just devastating, everything’s gone.”
Ms Clark said the flood had wiped out almost all of the sanctuary’s dog-food supply, with only two bags remaining, and the road “totally flooded [with] no access in and out”.
She said she feels “just broken”.
“There’s no electricity and nothing for the dogs. The bedding is soaking.
“No one, in the 25 years that they’ve been living here, has ever seen anything like this.
She added she was thankful for the crates in the loft.
“Today is just going to be a battle of trying to find clean bedding, and salvage what food we do have, and doing what I can,” she said.
Ms Clark said she now plans to build proper kennels in the loft.
