Is there any OTC Med. for eye watering?

Hi! I was hoping someone could tell me what I can use OTC for my Chubby's eye. It's just the one eye, left one, but every now and then it will water because of allergie's.
If there is, can you also tell me how much to use?
Thank you very much.
Chubby and I appreciate it!

If they are just watering from allergies there are eye wipes that petsmart sells you can use. Other then that, a warm washcloth is best. I wouldn't use an OTC medication of any kind on something as sensitive as the eyes unless a vet directly tells you to.
