Sabrina has had no formal medical training to speak of, and is far more likely to perform a cat scan in the front yard than one in a hospital - but for her owner, Curtis Young, the 11-year-old miniature pinscher has been instrumental in two life-saving diagnoses.
Back in 2005, not long after Young bought the playful pup at the flea market where he met her, Sabrina began behaving strangely around him. Without any clear reason as to why, she began to bite, scratch and lick at the back of his head whenever he'd sit on the couch.
"It was pretty annoying," Young tells Florida Today. "Very annoying."
Young says that at first he didn't give it much thought, chalking it up to his dandruff or possibly some skin condition. Eventually though, after Sabrina failed to let up, he decided have his doctor check it out just in case. And sure enough, a brain scan revealed a small, cancerous tumor inside Young's head.
The growth was still small enough to be removed, but Young insists that if Sabrina hadn't alerted him to it early on, he would have been dead within a year.
