This dog might be small, but he’s got a big heart for his best friend. 

Winston the dachshund proved his heroism earlier this month when his buddy Mijo, a 15-year-old chiweenie, was attacked by a mountain lion in Evergreen, Colorado.

Their owners, Sarah Moore and Lindsay Golden, told 9 News that the dogs got out of the house through an open door and within seconds, a mountain lion grabbed Mijo.

Instead of running away in fear, Winston chased the large cat and barked until it dropped Mijo and left, according to 9 News.

“This is his best friend, so I’m not surprised that when he was screaming, that he chased after him,” Moore, Winston’s owner, told 9 News.

“He’s got a lot of heart,” Moore added.

As soon as the mountain lion dropped Mijo, Moore and Golden rushed him to the emergency veterinarian. 

Unfortunately, the dog lost his right eye and had a seizure the night of the attack. Mijo could have some neurological damage, according to a GoFundMe page Moore set up to help pay for his medical bills.

As of Thursday afternoon, the page had raised over $11,500. 

Golden, who owns Mijo, told 9 News that Winston is a hero.

“[A] 20-pound dog with the courage of a 200-pound dog,” she said.
