Pannus in dogs is presumed to be hereditary and immune-mediated. UV radiation, high altitudes, and tobacco are pannus risk factors.
These variables might worsen pannus and make treatment tougher.
The most impacted breeds are German Shepherds and mixes. Greyhounds, Rottweilers, Belgian Tervuren, and Border Collies also get pannus. Any breed can get pannus.
Dogs usually get pannus between 4 and 7 years old. Pannus is usually worse in dogs that develop it early. Pannus in dogs over 5 or 6 is easier to cure and control.
Dogs with pannus often have these symptoms: An elevated red eye bulge A grayish-pink eye film Visible eye blood vessels
Dark brown eye pigmentation Eye tearing excessive Pawing or rubbing the eye Vision issues (walls, refusal to jump or play)
Cats' whiskers penetrate their cheeks and connect with tiny muscles and nerves that allow them to sense anything that touches them.
