Treatment entails giving your dog an antibiotic Eye drop and utilizing an Elizabethan collar to forestall your dog from rubbing their eye, causing additional damage. If it doesn’t heal, the eye might rupture or trigger scarring of the cornea, which can restrict the dog’s vision. Cataracts could be inherited or attributable to other ailments. One explanation for cataracts is diabetes, as the excess glucose causes the lens to swell. The lens can finally rupture and trigger uveitis, or severe irritation within the eye.
