Which statement describes common vision changes in aging dogs?

• A. Cataracts only
• B. Progressive retinal atrophy only
• C. Cataracts, progressive retinal atrophy, and reduced depth perception
• D. No vision changes occur with age

Answer: (C)

As dogs age, several parts of the eye can change, and these often occur together. Cataracts cloud the lens, reducing clarity of vision. Progressive retinal atrophy damages the retina over time, leading to gradual vision loss. In addition, aging can dull depth perception, making it harder to judge distances and navigate unfamiliar surroundings. The statement that includes cataracts, progressive retinal atrophy, and reduced depth perception captures both structural eye changes and the functional impact on seeing, which is why it’s the best description of common vision changes in aging dogs. The other options describe only one aspect or claim no changes occur, which doesn’t reflect typical aging.
