A five-year-old boy has been left 'shaken' after he was bitten by a Chihuahua while at a St Albans park.
Police are now trying to trace the owners of the dog after the child was bitten on the leg near the Inn on the Park in Verulamium Park on Sunday, April 13.
PC Stuart Francis said: "We would like to speak to the dog owners(s) so we can establish exactly what happened.
"The boy, who was with his grandfather, received a puncture wound and bruising to his leg. He was shaken by the incident and was given antibiotics and a tetanus injection."
The small long-haired Chihuahua, which was not on a lead, was being walked by a man who was with a pregnant woman, also carrying a short-haired Chihuahua.
He added: "The park was very busy on Sunday and we would like to speak to anyone who saw what happened or knows who the dog owner(s) may be."
Anyone with any information is asked to contact PC Francis on 101 quoting F1/14/1209
