Jon-Lic McLoughlin, 26, punched and kicked his 11-month-old puppy Lexi in a furious attack that left the dog dead..
Once McLoughlin calmed down after his outburst he attempted to cover his tracks by dumping the body in an area of trees near his home in Poole, Dorset.
However the court heard, a group of children found the dead dog which had suffered “blunt force trauma” leaving them “traumatised”.
“I get very angry and I don’t know what came over me”
A post-mortem carried out on Lexi’s body found she had also suffered laceration to her liver, blood in her abdomen and a stomach tear.
Mcloughlin, who had bought Lexi with his partner a month before the fatal attack, appeared at Poole Magistrates Court.
He pleaded guilty to “causing unnecessary suffering to a protected animal”.
During a police interview McLaughlin initially tried to blame Lexi’s injuries on a road traffic collision.
However, he later confessed to the killing, telling officers: “I get very angry and I don’t know what came over me”.
The death was reported to the RSPCA who brought the prosecution against McLoughlin to court.
Matthew Knight, prosecuting, said: “He punched or kicked the dog to death and dumped the body in some trees near his home.
“It was found by locals and upset local children who saw it. She had a laceration to her liver, blood in her abdomen and a stomach tear.
“It is likely that the dog did not survive for long.”
McLoughlin’s defence team argued that he was under significant stress at the time due to being a carer for his ill father.
Defending, James Moore said: “This episode of blind rage is where stress has got the better of him.
“This is not just some violent thug who thinks it is okay to treat his own pet poorly.”
During the hearing magistrate Martin Arthur told McLoughlin that custody was “not off the table”.
The case has now been adjourned until September 5.
Animal rights group PETA, have called for him to be jailed after discovering the news.
Elisa Allen, Director of PETA, said: “The pain and fear that this puppy must have endured are almost unimaginable.
“We implore Poole Magistrates Court to give Mr McLoughlin the maximum sentence, including prison time, counselling, and a lifetime ban on keeping animals.
“Because repeat offences are the rule rather than the exception among animal abusers – who often go on to harm humans – such acts must be treated with the utmost seriousness.”
