Dalmatian is spelled wrong as it should have an "a" instead of an "o", the up close photo of a labrador retriever looks like a great pyrenees, and the "collie" is more specifically a border collie. I also was a bit put off by the inconsistencies of accepted answers. The quiz took the answer "German Shorthair" for German Shorthair Pointer, and "Husky" for the Siberian Husky, but wouldn't take "Corgi" for Welsh Corgi. Also, probably too much time, just things to think about.
The labrador retriever looks a bit more like a golden, so I'd recommend changing it, but it works, the "greyhound" is a saluki, you should accept corgi for Welsh corgi which btw is specifically a welsh Pembroke corgi, dalmation is actually spelled dalmatian, and collie is a border collie, those two are different breeds. Besides that, good quiz.
