Dogs can develop styes just like humans do, both on the inner and outer side of the eyelid. The upper and lower eyelids are equally susceptible to infection. The inflammation in the glands at the eyelid base gives rise to a stye that can become extremely painful for your dog.

How do I get rid of the bump on my dogs eyelid?

Pet eyelid tumor treatment

A small, superficial, or benign tumor can possibly be debulked, and treated with cryotherapy using local anesthetic and sedation, while a malignant, full thickness, or large tumor may require general anesthesia and removal of a portion of the eyelid.

Will a dog stye go away on its own?

In most cases, a dog stye goes away on its own, so veterinarians usually try a course of washing, compress application and medication first. If it gets worse, however, or if it is severely bothering the animal and interfering with vision, a professional might choose to remove it manually.
