A boy and his dog graduated high school in Arkansas together, CBS Little Rock affiliate KTHV-TV reports. <br />Tyler McCready said he couldn't have graduated without his best friend, Sinatra. Both wore graduation gowns on the big day. <br />Sinatra is McCready's diabetic alert dog, trained to let McCready know when his blood sugar is low or high. <br />The two went to every class together, so Tyler made sure Sinatra's outfit looked good on graduation day. <br /> "His first one came in and it was little small, so we had to get it redone, but they got it done pretty fast," McCready said. <br />"That dog needs a Ph.D.," his dad, Jerry McCready, added. "He will call him and alert him to let him know his sugar is dropping. Usually, the dog is quicker than his diabetic equipment." <br />McCready wants to attend college at Full Sail University in Florida this fall, and Sinatra is going with him.
