My dog either got stung by a bee or biten by a mosquito IN the eye, his eye is all bright red and watering really bad, what can I do?

Have you called the vet? If my dog was stung by a bee in the eye ball, I would be taking him to the vet!

If it is actually IN the eye you need to get you dog to a vet asap.
Don't leave your dogs vision to chance.

Please get off your computer and go to the vet. There's nothing anyone online can do for your dog. This needs to be looked at by a professional.

Go to the vet asap.
