A teenager threatened to break the neck of his girlfriend’s puppy and then trashed her home.
Tim Brooks smeared dog dirt on the walls, threw gloss paint on windows and bleach on her clothes, in addition to smashing the television and a mobile phone.
Brooks, 19, of Eaves Street, North Shore, Blackpool, pleaded guilty to assaulting his then girlfriend and damaging her home.
He was bailed for pre-sentence reports with all options including custody to be considered by Blackpool magistrates.
He must not contact the woman or enter the road where her Bispham home is, as conditions of his bail.
Adrian Hollamby, prosecuting, said the couple had been in a relationship for two years when the incident happened.
On December 8, Brooks was in a bad mood because he had earache, the court was told. During an argument he elbowed his girlfriend twice in the back.
He then picked up the puppy and threatened to break its neck before going on a wrecking spree round her home.
When interviewed Brooks said he smashed his girlfriend’s phone because he believed she was texting another man.
He added the TV broke when he threw down a mallet he had in his hand and bounced into the set.
Steven Townley, defending, told magistrates: “The defendant said he was awake for three days suffering earache.
“He said he was provoked by the complainant when she indicated she had been seeing another lad.”
