Ms Price said they were given the two puppies they called Vixen and Comet and treated them for worms and gave them essential fluids and nourishment.
“Unfortunately, Vixen didn’t make it and we lost her,” she said.
“Comet is the bigger sister and seemed a little stronger and she’s been doing okay but it is very early days.
“We can let her go to one of our foster homes for more care now – she has a feed like, every 20 to 30 minutes – but we’re on hand if anything happens. She really is riddled with worms.”
Nobody knows who dumped the puppies but Ms Price appealed for anyone who may know to come forward.
“They were taped up in a rain-soaked box,” she said.
“Somebody surely knows them or if there are any more in the litter, or how mum is doing?
“We need to find who did this and they need to face the consequences – they could have gone to any vet, somebody would have helped them.”
The charity has since received plenty of offers to rehome Comet.
“I hope we can find who did this and Comet will be OK and be a Christmas miracle and keep going,” she added.
