An Urbandale police officer is being called a hero for rescuing animals from a house fire over the weekend.In a photo posted to social media, Officer Chase Breeser is holding up one of two guinea pigs he gave CPR to after firefighters brought their cage out of a burning home on Saturday. Neither one of the pets were breathing before his life-saving efforts, but he was able to revive them both."This incredible teamwork and compassion saved two lives that might have otherwise been lost," the department's Facebook post reads. "Big shoutout to Officer Breeser, the firefighters, and everyone involved for showing that heroism comes in all shapes and sizes."
