I know both are dqs, but what is the difference between the two? They both seem like the same thing to me (and it's not something I've run into in my other breed.)
Here is a pretty good article on the eyes in dogs and the different terms used and what they mean.
The definition for walleye here and in pixie's post is the common definition used when talking about dogs, but there is a second definition or walleye which is more commonly used with humans, but sometimes you come across in the dog world. That definition is when the eyes don't point straight but instead are pointed our or are crossed.
