A 14-year-old Maryland boy has been charged with animal cruelty after allegedly stabbing his 10-week-old Saint Bernard puppy to death, authorities said.

Anne Arundel County Police responded to a home in the 200 block of Mountain Road in Linthicum about 2 p.m. Tuesday. Officers found the teenager in his bedroom with the family puppy, which was covered in blood and laying on its side in the boy’s bed, police said.

The dog appeared to have been stabbed in the throat and stomach, police said. Next to the animal, at the foot of the bed, was a kitchen knife covered in blood. The boy appeared to have blood on his arms, legs and shorts.

Police said there were no prior animal control reports about problems with the dog, and there was no evidence that the puppy had provoked the boy prior to the stabbing.

The boy was taken into police custody but did not say why he stabbed the puppy, authorities said.

The boy, who was charged with animal cruelty on a juvenile citation, was taken to a local hospital for unspecified medical treatment and later released into his father’s custody. His name was withheld because he is a juvenile.

Anne Arundel County Animal Control took custody of the puppy’s remains.
