Pets can occasionally get foreign bodies in their eyes such as grass seeds, fish hooks, and even ingrown hairs and even eyelash disorders can act as a foreign body. Your pet will be quite uncomfortable trying hard to get it out. It is something that can possibly develop into an infection or even the loss of an eye so it's important to treat it as quick as possible. If the item gets stuck beneath the eyelid or is embedded into the eye you will need to seek emergency vet help.
