Missing 13-Year-Old Pitbull Lab Mix in Cranston

She is a pitbull lab mix, she is almost 13 years old. She is going blind. She was being fostered because my daughter is getting divorced, so her and her 3 boys are homeless, couch surfing until she gets settled. The person who was fostering her dog lives in a trailer, somehow her dog got out and now no one has been able to find her.
