A “resident” guinea pig at the West Shore shelter of the Humane Society of Harrisburg Area received a hero’s praise recently, credited with saving the life of a choking puppy by alerting staff.
Staff members heard frantic squealing and shuffling from the cage of Snowball, an albino guinea pig that shares space in a hallway with Bianca, a deaf white pit bull mixed puppy.
When staff arrived, they discovered that Bianca had tried to escape her crate by wedging her head through the door. When she became caught, she started choking and struggling to remain conscious. Bianca was quickly released from the crate door and is now fine.
“The dog got lots of hugs, gave us lots of kisses, and the hero enjoyed two carrots,” said Claudi Luci, an HSHA volunteer.
I volunteer at this place. Still not a big guinea pig fan. :)
