If you're thinking of adding a furry friend to your family this holiday season, Found Animals' Adopt & Shop encourages you to adopt an animal from its 12 Pets of Christmas list.

Statistics show that certain types of pets are less likely to be adopted — and therefore, more likely to be euthanized — than other animals.

Older animals, large dogs, Chihuahuas, black pets and those with special needs are just a few of the types of animals that are often overlooked at shelters.

To raise awareness for these pets and help find them homes, nonprofit Adopt & Shop staged a photo shoot with some of the adoptable pets from its stores.

Many of the images from the 12 Pets of Christmas are inspired by popular movies, such as "Up," "Castaway" and "Kindergarten Cop."

As part of the campaign, throughout the month of December, Adopt & Shop is offering $50 off adoptions of all its hard-to-place pets.

Take a look at some of the featured pets in the 12 Pets of Christmas and learn why an overlooked animal from one of these categories could be just what you need to make your holidays merry and bright.

Black pets — especially cats — are steeped in superstition, and their dark coats can make them difficult to photograph and therefore more likely to be overlooked by potential adopters. Don't let folklore or poor photos get in the way of adopting a great pet.

In addition to saving a life, there are several other advantages to adopting a senior pet. When you bring home a puppy or kitten, you don’t know how their personalities will develop, but with an older pet, shelter workers can tell you exactly what to expect.

Also, senior pets are likely already potty-trained and despite the saying, you really can teach an old dog new tricks.

Thousands of pit bulls end up in animal shelters because they're overbred, abandoned or abused, and with all the rumors circulating about these dogs, you may be hesitant to adopt one.

Some pets spend months or years in a shelter waiting for a home even though they're perfectly adoptable. Make such an animal's holiday wish come true by giving it a home this Christmas.
