People couldn’t look past this pit bull’s grumpy face — so this woman stepped in

Have you ever felt overlooked? That was the case for Sheldon, whose grumpy face — and the stigma attached to being a pit bull — kept him from being adopted.

All it took was for one shelter volunteer, and one adopter, to see him as he really is: a pup of perfection.

This is Sheldon meaning business.

Sheldon arrived at the Arizona shelter just a few days after Christmas. He is a sweet, loving boy who already knew basic commands like “sit” and “paw,” so it seemed like he’d been somebody’s pet.

But that somebody didn’t collect him. Whether it’s because of his grumpy face, or because that grumpy face is attached to a pit bull’s blocky head — a head shape associated with a whole lot of untrue negative stereotypes — for a long time, nobody else wanted to take Sheldon home, either.

“Unfortunately, no one came for Sheldon,” Melissa Gable, spokesperson for Maricopa County Animal Care & Control, told TODAY in an email.

Sheldon can’t believe he was overlooked for so long, either.

Shelter volunteer Heather Haltmeyer saw promise and opportunity where others had seen…less.

“He is definitely a sweet dog!” she told TODAY.

Haltmeyer specializes in taking pictures of dogs who need some extra help getting noticed by potential adopters.

In late January, she took some photos of Sheldon that would best show off his curmudgeonly mug, and darling personality. They were posted to the Maricopa County Animal Care & Control Facebook page, with this excellent come-on:

“GUYS! Look at this face!! We may be biased, but we think Sheldon should be a doggy celebrity with all those expressions! Think of all the fun you could have taking pictures of him if you adopt,” she wrote.
