My dogs swollen

Question
I took my dog outside so she could pee and I left her out there for about an hour.  When she came back in her mouth was swollen. As the time went by about 2 hours later I noticed her who head was getting swollen including her hears and her private areas. What should I do? Should I be worried?

Answer
Thanks for your question.  Take her to the vet right away you should be worried she could have gotten bit by a bug that she is alergic too and might have swelling of the brain.  She could also be retaining fluid inside that could cause server brain damage.  Hope this helps.
