Glaucoma is an eye disease that affects many humans but it doesn’t only affect us. It can also affect our dogs.  It’s caused by a build up of fluid in the eye and is one of the most common causes of blindness in dogs.  Did you know that Glaucoma strikes about 1 out of every 200 dogs?  Some breeds are more at risk than others. They are Cocker Spaniels, Terriers,  Basset Hounds and Beagles.  The problem with this disease is that the symptoms are hard to spot.  As with humans, an early diagnosis is critical to preventing blindness.  Some signs that you may want to look for are cloudiness, redness or a glassiness in a dog’s eye.  Some other symptoms may include tearing, a sensitivity to light or a dilated pupil.  If you notice any of these problems with your dog, have him checked out by your veterinarian. The sooner the better.  There is pet medication that can help if the disease is diagnosed early on.
