Two loose dogs attacked a passer-by walking their own dog in an incident in Higham Ferrers last Friday morning (March 14).
Northamptonshire Police said the incident, which happened at about 9.20am, was currently under investigation.
A spokesman for the force said: “We were contacted after reports that two large dogs were on the loose in Bates Close, Higham Ferrers, last Friday shortly after 9am.
“The two large dogs apparently got out of a property and approached a smaller dog which was being walked by its owner nearby and attacked it.
“The owner of the small dog stepped in and picked up their own pet in a bid to protect it.
“However, they were then bitten on the hand by one of the large dogs which was on the loose.
“Officers attended the scene and found that the two dogs had been returned to their home.”
Police said the person who was bitten had suffered minor injuries.
The victim visited a GP to have the injury treated.
The spokesman added: “Our inquiries into the incident are ongoing.”
