Baltimore, Maryland – A rabid beaver inflicted serious injuries on a 13‑year‑old boy named Dominick in a shocking and violent unprovoked attack.

The teenager was reportedly diving in a lake at Cunningham Falls State Park, watching a few fish underwater.

It was a lake where the boy had been swimming since childhood and where no beavers had ever been seen by his family.

"His mom and younger brother were on shore when they watched in horror as this 4-foot-long beaver (not a cute little cuddly beaver – this thing was as big as his 8 year old brother) came out of nowhere from the deep of the lake, beelined straight toward D, and began biting and attacking him," Dominick’s Aunt Leigh Cebula wrote in a fundraising appeal on GoFundMe.

"He did not provoke it, poke it, or mess with it in any way. This was completely unprovoked."

The 13‑year‑old was taken to the hospital due to potentially life-threatening injuries. Pictures released from the clinic show deep gash wounds to his chest and arm.

One reason the beaver might have been so aggressive: the rodent was infected with rabies, as reported by Fox News. The animal was captured and euthanized.

"It was so traumatic. He was lifeflighted to Johns Hopkins because the paramedics were worried his lung was punctured. Luckily it wasn't," his mother Alishia Cebula told Fox.

"He is doing much better. He just had surgery on 9/4 to repair a severed nerve in his finger... He had a lot of appointments, especially with the rabies vaccines he had to get. Thank God for the vaccine."
