Hundar och andra djur- Vad de betyder för oss, kompisar i vår stressiga tid.

Hi Celia Sager, Dog's eyes are amazing. Many people ask questions about what dogs can see. Today I thought I'd talk about a few questions that clients ask about canine eyesight (and one they don't but should). Just a warning - there is a photo below of one type of injury; I've included it to help readers learn how ulcerations look. 1. Do dogs see in color? Answer: Dogs do see in color, but their perception of color is not the same as it is for people. They cannot distinguish between red, orange, yellow or green. They can see various shades of blue and can differentiate between closely related shades of gray that are not distinguishable to people. 2. How do dogs see compared to us? Answer: When comparing dog and human vision, people are better at depth perception, color perception and seeing small details of an object. Dogs are better at seeing in dim light, responding to an image rapidly, and detecting the slightest motion. They also have better peripheral vision. 3. Do dogs get eye problems? You bet. Dogs can get many eye disease including glaucoma, inflammation in the eye, and corneal ulcers. Eye injuries are common - many of which can be prevented. They frequently occur while bathing the dog, either when the shampoo irritates sensitive eye tissue or they rubs their eyes and create an ulcer. Learn more about corneal ulceration in dogs. Here is a photo of a dog with a superficial corneal ulcer. The ulcerated area appears green due to a fluorescein stain used to determine the size and depth of the damage. This stain is used in many veterinary procedures and is very helpful during treatment. Read more about it here Signs of an eye injury include squinting, rubbing at the eye, or redness in the surrounding tissues. Squinting is usually a sign that something is wrong. Learn about this important symptom here. If you see any of these signs, please call your vet. Another thing you can do is to prevent your dog from rubbing at his eye until you get him to medical help. Until next time, Dr. Jon P.S.: Don't delay if you think your dog has an eye injury. Tissues around the eye are very sensitive and it doesn't take much to result in lasting damage.
