SSPCA bosses are appealing for information after a poorly dog found ditched in Paisley had to be put to sleep.
The elderly French Bulldog had to be destroyed after it was found seriously ill in the bitter cold outside shops in the town's Caledonia Street.
A member of the public raised the alarm after finding the stricken animal at around 1am on February 14.
Mystery surrounds the movements of the starving dog had no use of his hind legs, as well as a severely ulcerated eye.
Scottish SPCA chief inspector Laura McIntyre said: "The dog was a male, fawn French bulldog. We estimate him to be around 11 years old and he was not neutered.
"He was microchipped to an address in Falkirk but was reported missing from this address in June 2021.
"The dog was in generally poor condition, and was suffering from a severely ulcerated eye. He could not use his back legs and would not eat.
"On veterinary advice it was decided that the kindest thing to do would be to put him to sleep and end his suffering."
She added: "We’re keen to find out how the dog came to be in the area in such poor condition and why he was left alone when he was clearly unwell and in pain.
"There is a vet on this street and we are unsure if someone has tried to leave him outside of the vets hoping he would be found. However, this is not the correct procedure to follow.
"If anyone has any information on this incident they can contact our confidential animal helpline on 03000 999 999."
French Bulldogs have grow in popularity over recent years but are known to suffer from a range of health conditions which can be costly to rectify, including spinal dysfunction and disc disease.
