You did exactly what I would have done. I'd hit her for hitting her dogs..arg..it just pisses me off..I know it's not right but hey, she didn't do the right thing by yelling at your mom like that. The people here are good about asking if it's alright..but..come on..it's rude to give another person's dog a treat???!?!?! what's wrong with her..if she didn't want her dogs to have it, she could have just said "oh no, i don't want them having that" or something... Rude lady!
