My dog is allergic to grass. She is white and I noticed her getting very red and very irritated eating and licking her paws so i took her to the vet and he told me that dogs have allergies as well. It is amazing how well she looks when I don't take her in the grass, but it is hard because I am surrounded by many acres of grass all around my house. My vet suggested over the counter medication that works very well but i hate giving her any type of medicine!
