Just like in humans, allergies frequently result in red eyes in dogs. Your dog's eyes may turn red, itchy, and watery if they are allergic to pollen, dust, or other environmental allergens.


Your dog's eyes may turn red and puffy if they have been harmed, such as by getting something in them or being struck by anything.

Dry Eye 

When the eyes do not generate enough tears to keep them moist, the condition is known as dry eye. The eyes may become gritty, inflamed, and red as a result of this.


The thin membrane that borders the eyelids and covers the white of the eye is called the conjunctiva, and it can become inflamed, resulting in conjunctivitis, commonly known as pinkeye. Bacteria, viruses, and allergens are all potential causes of conjunctivitis.


A dangerous eye condition called glaucoma can lead to an increase in ocular pressure. This may cause blindness by harming the optic nerve.

It's crucial to take your dog to the vet for a diagnosis if you notice that their eyes are red. The best course of treatment will be suggested by the veterinarian when he or she has identified the reason for the red eyes.
