The couple rushed Clarice to the veterinarian the next day. She has required more than $3,000 worth of surgery to remove the nails from her stomach, WISC reported.
Lake Delton police Sgt. Steve Smith confirmed detectives are looking into the case but said police aren't yet able to share details about the ongoing investigation, WISC reported.
Deakin said he doesn't know why anyone would purposely try to hurt dogs like Clarice, but he hopes whoever did this turns him or herself in.
"Whoever did this, you know, you've got 50, 100 pet owners in that complex absolutely livid ... go turn yourself in, make it easier on yourself," Deakin said. "Otherwise, I don't know how you're going live in that complex."
The couple set up a Go Fund Me page to help with Clarice's veterinary bills. Nearly $2,000 had had been raised as of early Friday morning.
