An Arizona man's dog didn't live up to being man's best friend, according to a report.

While sleeping, Frank Monarrez's dog chewed off three of his toes. Because he is diabetic, he didn't feel a thing, WEWS-TV reported.

"The doctor even said she's been doing this for years and never seen a case like this in her life, never. This is the first time she's seen anything this bad," Monarrez said.

He is an amputee and his dog Baby D could have made him a double amputee, but he is handling the situation well. He said his entire foot could have been gnawed off.

"It's laughable after the fact, but it wouldn't be laughable if it's more serious and I had to end up having my foot amputated then I'd be a double amputee and that's one thing I didn't want," he said.

Baby D has been quarantined. The county will keep her for 10 days and then she is likely to be returned to Monarrez's son.
