The man was walking his own dog through Filey Country Park when he was bitten by a Staffordshire bull terrier-type breed on Sunday May 8 at 3.20pm.
The Staffordshire bull terrier-type dog approached the man and his dog, and bit the owner on the right forearm, resulting in a wound that needed stitches.
The owner of the dog is described as being aged in his early 50s, with glasses and shaven hair, and the dog itself is described as a brindle and brown coloured Staffordshire bull terrier-type dog, with a white chest.
Police are now appealing for witnesses and information, in particular, information about the owner of the dog.
