Four-legged Philly police officers just got an extra level of protection.

The Philadelphia Police Foundation nonprofit announced Wednesday that they had received 23 canine body armor vests, thanks to a $22,000 donation from local philanthropist Joanne Berwind.

"It will be the first time in many years that each canine will have its own, specially-made body armor," the foundation said in a press release.

Every patrol dog will have its body armor custom fitted to its size. Four K-9s that do not go on patrol, an explosives dog and three cadaver dogs, won't get suited up, the Daily News reported.

“The Philadelphia Police Foundation is grateful to Joanne Berwind for her generosity and concern for the safety of the Canine Unit’s four-footed police officers,” said Police Foundation Board President Maureen Rush in a statement. “I know the entire police force, especially the officers assigned to the Canine Unit, join me in thanking her for her actively stepping up and assisting the Police Department through the Police Foundation."
