Red eyes can be caused by several factors, with varying degrees of severity. As with any concerns you might have about your furkid, it never hurts to get a second opinion from your vet.
Whether it’s pollen, dust, or even mold spores, allergens for dogs can cause plenty of unpleasant symptoms, including red, itchy eyes. Eyes become swollen and watery, which in turn can lead to further issues such as conjunctivitis. Itchiness can also cause pups to paw and claw at their face, or rub their faces against the ground or furniture. This can cause damage and irritation to the eye from scraping and rubbing.
Dry eye also known as Keratoconjunctivitis sicca is typically caused by inflammation of a special gland that helps your pup make tears. With their tears on the fritz, your dog’s eyes get very dry and inflamed, which causes them to appear red. This can be very painful for your pup and can make the cornea very vulnerable as well, which can lead to even further vision issues as a result.
If your dog has mucus in the eye, lots of blinking, swelling of the eyelid, and the third eyelid peaking out it could indicate dry eye. Along with gland inflammation, dry eye can occur more often in certain breeds of dog.
If you’ve noticed any severe swelling along with redness, it’s a good idea to talk to a vet right away. This can be a sign of glaucoma, which is a very painful condition. Glaucoma happens when certain fluids in your dog’s eyes cannot drain the right way because of swelling. Glaucoma causes a lot of pain, which can be hard to recognize at first. If your pup is showing signs of headaches, like disinterest in play or loss of appetite, reach out to your vet as soon as possible.
Glaucoma has two different types. Primary glaucoma happens when genetic conditions prevent proper drainage for the eye, causing backup and swelling. Secondary glaucoma is typically caused by trauma or injury to the eye, causing inflammation.
