AUTHORITIES are trying to trace the owners of a dog which may have been abandoned between Helensburgh and Luss at the weekend.

The severely emaciated Staffordshire bull terrier was found on the A818 on Saturday morning and was handed in to police in a neglected state after being spotted wandering alone on the Blackhill.

The dog, named Dexter, was collected by a passer-by who reported that the extremely underweight pet barely had the energy to climb into his van.

Dexter spent the night at a local veterinary centre receiving fluids and those looking after him say they are hopeful of nursing the lovely-natured pooch back to full health.

Scottish SPCA inspector Laura McIntyre said: “He is in a terrible state and has severe pressure sores on his back end, near his tail.

“We are keen to speak to his owner as soon as possible or anyone who can tell us more about this boy.

“He received much needed veterinary treatment and is currently being cared for at one of centres.

“We would urge anyone who recognises him or knows anything to contact our confidential animal helpline on 03000 999 999.”

Police say they are continuing enquiries to trace Dexter’s owners.
