A man stabbed his girlfriend's dog to death after he claimed it would always take her side during their arguments, police said.

Mike Lado, 26, was arrested Wednesday for animal cruelty after he fatally stabbed his girlfriend's Boxer Lab mix named Blue with a knife in Lee High, Florida.

Lado, who had been drinking earlier that night, started fighting with his girlfriend and attacked Blue when he barked and growled at him, she told police.

Lado had been out drinking before he returned home to his girlfriend and got into an argument, according to the Lee High Sheriff's Office.

When the argument ended, Blue followed Lado to the kitchen, according to the girlfriend, FOX reported.

The girlfriend said Blue wasn't being aggressive, although he did bark and growl at Lado, who then grabbed a large knife and stabbed the dog twice.

Detectives found a pool of blood in the kitchen, and a trail down the hallway that suggested Blue tried to get away.

The dog eventually died from bleeding to death, and Lado was arrested on a felony animal cruelty charge.

Lado said he was upset Blue would 'always take her side in arguments' officials said.

He is being held in Lee County Jail on $5,000 bond.

The county Domestic Animal Services had been called multiple times in regards to Lado and Blue, according to NBC.

The girlfriend adopted Blue through the Gulf Coast Humage Society, and CEO Jennifer Galloway told NBC, 'It was a big kick in the gut' to find out what happened to him.
