A Longmont man is facing animal cruelty charges after police say he kicked and killed his girlfriend’s puppy last weekend.

Jon Guthery, 37, was booked into the Boulder County Jail early Thursday on suspicion of animal cruelty, a Class 6 felony.

According to an affidavit, a veterinary clinic called Longmont police to report a puppy named Beau had died from suspicions injuries on April 26. A vet told police a woman brought the puppy in with contusions on its lungs. The puppy died before it could be transferred to an emergency clinic.

A necropsy showed the puppy had “significant trauma” on three sections of its body and bruising on several of its organs, as well as a broken jaw.

Police found the owner of the puppy, who said she believed her boyfriend, Guthery, was the one who kicked the puppy. She said she had taken the puppy to work that day and fed it peanuts, which later gave it diarrhea at their home and that might have angered Guthery.

Guthery told officers he had just gotten out of the hospital while trying to get off methamphetamine and did not remember doing anything to the puppy. But Guthrey reportedly called 911 the day the dog died and admitted during the call he kicked the puppy while he was “freaking out” and detoxing.

Friends of Guthery who came to check on him also said he admitted to kicking the puppy.

Guthery’s bond was set at $250 after an advisement hearing Thursday and is slated to appear for a formal filing of charges on Tuesday.

He has a prior conviction for criminal mischief as well as numerous traffic violations in Boulder, Larimer and Weld counties.
