Meet KJ!!! 

"I am a 7 yr old loving boy, about seven years of age. I love to hang with people, sometimes I even like to make believe I am one!! I am great on a leash and love to go for walks. My foster mom takes me on runs and I can totally keep up.  I am just looking for a furr-ever family who’d love to hang out with me, too!!"

KJ would make an excellent hiking or running partner.  He loves kids and other dogs. However, he will not do well with cats.  

KJ is house trained, crate trained, walks well on a leash, rides well in the car, knows how to use a doggy door, and knows basic obedience commands. 

If your family is looking for a four-legged buddy to take running, sweet KJ could be the guy for you!

About Underdog Rescue of Arizona

About Our Rescue Group...

Underdog Rescue of Az is an all volunteer organization dedicated to the rescuing and re-homing of abandoned and/or abused dogs.

We are a foster-based rescue, and do not maintain a physical base of operations. All of our animals are placed with loving, caring safe foster families until they are adopted. We are also an "All Breed" rescue, and do not discriminate based on breed, age, size, etc.

Underdog's mission also includes educating the public on the issue of animal welfare. We strive to promote shelter reform, spay and neuter education and emergency rescue information & assistance.

Come Meet Our Pets...

We attend multiple adoption events throughout the valley during Spring and Fall.
If you are interested in a specific pet, please complete our adoption application found on our website and we can then coordinate a meet and greet.

Our Adoption Process...

All potential adopters will be required to complete our Adoption Application, read and sign our Adopting Policies and Procedures, and participate in a home visit by one of our adoption representatives. Our Adoption Application is located on our website:

We also have a mandatory two-week Foster With Intent to Adopt trial period for all animals in order to be certain the pet is a good fit for your family.

Our standard adoption fee for dogs is $200; puppies are $250.

Non-standard fees do sometimes apply. Puppies younger than six months may have a higher fee. Designer dogs, purebreds, and other toy type breeds may also have higher adoption fees than the standard $200.

We do, however, have discounted fees for dogs that are seniors, a pair of dogs adopted together, or cats. If you are a veteran or an active duty service member, please ask about our partnership with Pets For Patriots.

All Underdog pets are spayed/neutered, up to date on vaccinations and microchipped prior to adoption.

We are a 501c3 non profit, your donations save lives and are 100% tax deductible.
