Dog Eye Ulcers. A dog eye ulcer is usually called a corneal ulcer. A corneal ulcer is an abrasion to the top layer of tissue lining the cornea which is the clear part of the eye. Canine Corneal Ulcers are the third most common eye problem in dogs. Many eye ulcers are caused by trauma from foreign objects like fox tails and seed hulls from grass and weeds that can lodge under the eyelid. Scratches resulting from rough play between new puppies and kittens are also a common cause.
Definitions of a standard. One dictionary definition that comes close to ETSIâs interpretation is: âa document specifying nationally or internationally agreed properties of manufactured goods, principles for procedure, etcâ.
A standard is an ideal or set of criteria that you use to judge things against. Colleges have certain standards for applicants, like a minimum SAT score or an above average grade point average. If you complain that the soup isn't up to your standard, you're comparing it to an ideal and finding it lacking. (Just don't be surprised if the chef then accidentally spills it in your lap.) The economy used to work by the gold standard, where one dollar equaled a fixed amount of gold.
