The Scottish SPCA is appealing for information after a dog in an “extensive amount of suffering” was found in Paisley on May 14.
The female, Staffordshire bull terrier dog had a hugely inflamed and ulcerated mass on her lip when she was found in Ferguslie Park.
She has been described as an older female, mostly dark brindle in colour with a white chest.
The dog was not microchipped or wearing any tags.
The vet discovered an “extremely painful” inflamed and ulcerated mass on her lip, which affected her teeth and had most likely hurt her for a long period of time.
She also had overgrown nails and a number of other health conditions which were causing her an extensive amount of suffering.
Due to the severity of her condition she was put to sleep.
The charity is now appealing for help in tracing the owner.
Scottish SPCA inspector, Isla Bell, said: “Sadly, veterinary advice was given to put this dog to sleep due to the severity of her condition, as there was no way to fix the amount of pain she was in.
“If anyone recognises this dog or has any information on this incident they can contact our confidential animal helpline on 03000 999 999.”
