Luis Ocasio was left in tears after he said his next-door neighbor unfairly shot and killed his dog on Sept. 2, due to a neighborhood dispute.
Ocasio said his neighbor told him he shot the dog because he claims the dog killed his cat three days earlier.
But Ocasio said his neighbor never came over to discuss the incident, never called police, or called Cleveland animal control.
"For him to just come over and shoot my dog is really upsetting," said Ocasio.
"I didn't believe that somebody could actually stoop that low and hurt an animal, instead of talking to me about it."
"Please let the APL, make reports, call the police. Actually, take efforts to do it the right way, and not just unload a gun where there's kids that play every single day."
Cleveland Animal Protective League President Sharon Harvey told News 5 guns are not the answer when there's a dispute over pets.
Harvey said a person convicted of unlawfully using a gun to kill or injure a pet could face a fifth degree felony, and up to 6 months in jail.
"There is no dispute that should be ended with a gun," said Harvey.
"First thing you do is report the incident to the proper authorities, so that they can start the process of investigating the incident, and make a determination if that animal is dangerous or vicious."
The Cleveland APL is conducting a full investigation into the case.
The neighbor involved refused to give comment when News 5 tried to reach him by telephone.
News 5 is not naming the neighbor because has yet to be formally charged in the case.
