"Thankfully we don't have too many of these, we have kittens in boxes on the front door but not puppies dumped in a bag," she said.
"If people are wanting to get rid of animals, we advise they ring us, we will give advice for them to try and re-home them themselves but if they're having difficulties definitely ring us, don't just dump them."
The five puppies were sent to Animates pet shop on Friday.
"We have a good relationship with them and I'm pretty sure they will find a good home."
