Armed police were deployed to Saumarez Park this afternoon after the Staffordshire Bull Terrier launched the attack.
Two dogs were taken to a vet, one with serious injuries, with the attack prompting the armed officers to attend following multiple 999 calls.
Officers took over from members of the public who were containing the dog, but it still behaved in an extremely aggressive manner according to a Guernsey Police statement.
Guernsey’s States vet attended and on his advice authorisation was given to firearms officers to ‘dispatch the dog and neutralise the threat it posed’.
A Bailiwick Law Enforcement spokesman said: ‘We are establishing the circumstances around how the dog came to be attacking people in the park. We are liaising with the owner of the Staffordshire, and anyone with information is asked to contact us on 725111.
‘We would like to commend the brave actions of the public who intervened by restraining the dog as emergency services were en route – their actions undoubtedly prevented further injury.’
