Police and RSPCA officers have raided two properties in Buckinghamshire in a crackdown on dog-fighting.
They executed warrants under the Animal Welfare Act at properties in Bachelors Way and Tom Scott House in Chesham on Wednesday morning.
Thames Valley Police said a dog seized from the Bachelors Way property had been passed to the RSPCA to be examined for injuries.
A man, 28, was arrested on suspicion of keeping a dog bred for fighting.
He has been bailed to report to Aylesbury police station on 8 August.
Pc Hayley Goodwin, from the neighbourhood policing team, said: "This is the second series of warrants we have carried out in the area after residents raised concerns to us about possible dog-fighting.
"I hope this sends out the message to the community that we will act on information we receive and will continue to pursue offenders and conduct warrants to catch those involved illegal activity in the area."
Officers are appealing for anyone with information about dog-fighting to contact them or Crimestoppers.
