Thanks, Krista.

No, the dog who attacked her wasn't a stray. Some guy was walking his two dogs (a Rottie and a Pittie) without leashes on (he didn't even have any leashes with him) and they were running around totally out of control. His Pit came running across the field and grabbed Tango by the neck, shaking her. She didn't even warrant the attack, as she had made no eye contact with the dog and was walking very calmy, tail down, etc. beside me on her leash. She didn't have an aggressive posture at all. The dog's owner didn't do a thing about it and came slowly walking across the field, called his dog once and carried on down an alley without a care in the world, while in the meantime, his dog was still on Tango and I was trying to get him off (finally he did let go and another man grabbed the dog and helped me). The dog's owner didn't apologize or anything, just continued walking, assuming his dog would follow I guess. He finally came back to get the dog and told me I should have my dog under control and left. People like him shouldn't even own dogs, let alone the two breeds he had.
