RaeLynn is introducing fans to her service dog. She told "People" magazine, Jazz is trained to detect changes in blood sugar levels. RaeLynn has Type One diabetes. Jazz has been a part of her family for just over a year. He came from Global K9 Protection Services in Nashville. RaeLynn has another dog, a Chihuahua name Dolly. She says, there may be a noticeable size difference between the two animals, but Dolly is the boss. She says Jazz adores Dolly, but "she picks and chooses when she adores him." RaeLynn added, "if she growls at him, he will get off his bed and let her have it."
