Found Brindle Dog in Mesa - Sweet & Playful

I hit this pup in my car today. He has seen a vet and is not seriously injured, but may be sore. He is not microchipped and had no collar. We checked the neighborhood homes with no luck. Signs will be posted tonight. Sweet and quiet, but playful and does well on the leash. Great temperament. Young intact male, beautiful brindle color with white on his chest. He is ~40 lbs, young dog, maybe 3yrs old.
