Teen's service dog gets his photo in the yearbook: 'He brightens everyone's day'

A dog may just be voted most popular pup at a Virginia high school after his photo appeared in the school yearbook.

Alpha, the 3-year-old dog, is 16-year-old Andrew "A.J." Schalk's service dog that has been attending school with him at Stafford High School for the past year and a half.

Schalk suffers from Type 1 diabetes and Alpha alerts his owner if his blood sugar is dangerously high or low.

"It's been absolutely fantastic," Schalk told InsideEdition.com. "He's turned into such a positive thing for me to have being diabetic and to take around the school."

And everyone else loves him too.

"[He] brightens everybody's day. All the teachers I have look forward to seeing him, just seeing this adorable little puppy walk around," Schalk said.

Schalk said Alpha gives him a paw to notify him if he is in danger and has saved his life on multiple occasions.

"Being diabetic and having a disability, you wouldn't think that'd be something positive, but taking him to school every day and having everyone react so positively to him has had a positive effect on my life," Schalk said. "It's changed it into something for me where I am excited to take him to school."

Students were happily surprised when they noticed the pup in the yearbook.

"Well I had just gotten my yearbook and was flipping through when I noticed a dog, I realized it was AJ's service dog and I thought it was so cute," Diana Bloom, a student at the school, told InsideEdition.com. "He has a very important job and works just as hard as any other student so he deserved it."

Alpha wasn't the happiest about having his photo taken in front of the giant yearbook camera, Schalk said, but his picture was priceless. Alpha also received a school ID card.

"On picture day, I went and took my picture. I moved out of the way. They lowered the camera a little bit and took his picture," Schalk said. "He did fantastic. He's a great dog."
