Missing Male Pitbull/American Bulldog Mix named Bam

Our dog Bam went missing on Saturday July 29th at approximately 7pm at Village Green Dr and Woodbine Rd while being watched by a friend. Bam is a pitbull mix that is 1 year old and weighs approx 70lbs. Bam is primarily white with blue spots on his body, most significantly a white stripe that goes down the middle of his face. He was wearing a Herm Sprenger choker collar when he got away and was attached to a red retractable leash. Bam is an extremely nice dog with a great temperament, he gets along well with people and other pets. He does have skin allergies which require grain free food to prevent breakouts and he also has callus on his elbows due to his very sensitive skin. Please provide any information you can to help bring our pup back home because we miss him tremendously. Currently offering a reward of $5,000 with no questions asked upon return.
