Cataracts cause progressive vision loss in dogs. Understanding when surgery is appropriate and what welfare outcomes to expect helps owners make informed decisions.
Cataracts create a welfare assessment challenge because dogs adapt to vision loss remarkably effectively. A dog that appears to navigate well and maintain a good quality of life with cataracts may not require surgery, particularly if they are elderly or have other health conditions that increase surgical risk. Conversely, cataracts in young dogs, or rapidly progressive diabetic cataracts, significantly impact quality of life and benefit substantially from surgical intervention. Welfare-optimal decisions balance the restoration of vision against surgical risk.
