Why is my dog's eye red, painful, and has a white spot on it?

Pet's info: Dog | Beagle | Female | spayed | 11 months and 28 days old | 25 lbs

Hey there! My beagle, Maggie, is experiencing some eye problems. Her right eye is bloodshot red in the whites of her eyes, and there is a white thing (not a worm) on her eyeball or skin, I can’t really tell. She is keeping that eye closed at times, and I think it is bothering her. Help me, please!!

This is not specific to any one disease, but is suspicious of uveitis, which is often due to an infection, or other disorder within the eye. It's difficult to tell what the white thing is without seeing it, but it's likely related to the eye disorder. This could also be due to some disease affecting the cornea, which is the outside of the eye. The fact that she's keeping the eye closed indicates that she is in a great amount of pain - these conditions are often very painful. Considering this and that these conditions have potential to do irreversible damage to the eye, I recommend taking Maggie to a veterinarian as soon as possible. It's likely not an emergency, but I wouldn't wait longer than 24 hours to have her evaluated by a vet. For now, you can flush the eye with normal saline. Saline flush can be bought at the pharmacy, or supermarket in the eye care section. Flush the eye 3-4 times daily and gently wipe away the discharge with a warm/moist cotton or cloth. Below is a link to a good video that demonstrates how to flush the eye. https://www.youtube.com/watch?v=_lXVNMcPzhs For more information about the suspected conditions, I recommend you read the articles at the links below. https://vcahospitals.com/know-your-pet/uveitis-in-dogs https://vcahospitals.com/know-your-pet/corneal-ulcers-in-dogs I hope that helps and Maggie gets better soon.
