My dog's eye is bloodshot and he's pawing it. Should I worry?

Poor Blue! It sounds like he has an eye infection. It's important to have any eye infection examined and treated promptly, as untreated eye infections can lead to vision loss. I would take him into a vet now for an exam. The vet can confirm the eye infection, and can give him an antibiotic eye ointment to treat it.

Monitor for scratching or pawing, excess weeping or tearing, redness, swelling or squinting. If any of these symptoms are noted, he needs to see a vet as soon as possible to diagnose and treat a potential eye injury. Put an e-collar on him until he goes to the doctor.

It's most likely an eye infection, possibly conjunctivitis. Taking him to the vet now is great, before he damages the eye teslf by rubbing and scratching. Your vet will do an ophthalmic exam, part of which may be putting a dye in his eyes and examining them under a black light to look for scratches on his cornea. Based of the results of the exam, it will allow your vet to know just what is going on and how best to treat it.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be due to an eye injury or conditions such as a corneal laceration, corneal ulcer, uveitis, conjunctivitis, dry eye (also known as KCS), among many other conditions. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. Further therapy would be based on the findings. Good luck and best wishes!

This can likely wait until tomorrow and not need an emergency visit. He is super handsome! Have a good day!

The tearing and discharge may indicate an infection or injury. You would need to have Tobby physically examined by your veterinarian or a veterinary ophthalmologist to diagnose the underlying cause. The appropriate treatment can then be administered. In the meantime, place an e-collar (cone) on him to prevent pawing or rubbing until he sees the doctor. A warm, moist washcloth can be used to gently clean around the eye itself. Schedule an appointment sooner rather than later to prevent unnecessary pain or potential permanent damage to the eye.

Those eyes look pretty irritated, and I would be concerned there is a scratch or injury/reaction to the eye from the dust. I would try to keep the eyes cleaned and clear, and if they continued to swell or don't improve, seek veterinary care to treat any allergic reactions or injuries.
