Dogs have an exceptional sense of smell, but when it comes to their eyesight, they don’t see 20/20. In fact, our canine companions operate at around 20/75 vision, and that number tends to decline with age. No matter how old your dog is, however, vision problems can come into play and affect his quality of life.
 
Dogs are adept at adjusting to changes and poor eyesight will only become apparent when your pet starts making big mistakes. Even dogs with just 20 percent of their original eyesight can continue functioning as normal, thanks to their other senses and ability to memorize the floorplan of your house. Here are a few signs your dog’s vision may be declining:
 

When you throw a treat to your pet, he does not see it.

He is reluctant to go up or down stairs, jump off the bed or go outside at night.

When you move furniture, your pet bumps into it, and he hesitates in unfamiliar places.

Your dog only registers food as edible when he’s close enough to smell it.

There is a fuzziness in or on your dog’s eyes.

  
フィドのビジョンが悪化しているかどうかを判断する最良の方法は、彼の正常な視力が何であるかのベースラインを確立することです。犬の視力は私たちの視力とは異なるので、これは難しいかもしれませんが、いくつかの非公式なテストで何が自然であるかを判断して、変更を追跡することができます。 1つの方法は、親しい友人が遠くから彼に近づいているときにあなたの犬を観察することです。彼が反応するときに友人がどのくらい近くにいるかに注意してください。これは彼が見ることができる距離です。または、あなたが自分の好きなおもちゃでゆっくりと歩いている間に誰かにあなたのペットを抱かせて、それを見て反応する距離をメモします。これらの大まかな測定は、ペットのビジョンが将来低下しているかどうかを確認するための簡単な在宅テストのベースラインを提供します。
 
If you notice that your dog’s eyes are failing, discuss treatment options with your veterinarian. Loss of eyesight can be caused by aging, infections or hereditary factors, but diabetes and other conditions can also impact vison and there may be supplements, dietary changes and medications to help your pet. You can make life easier for a dog with bad eyes by providing him with a safe home environment. Clear walkways and leave furniture in place—or, if you must rearrange a room, do so gradually to help your dog adjust. This way, even older pets or those struggling to see can enjoy a high quality of life.
