Quick Ring Species Question

Can dogs be considered a ring species? Not too many cases I've seen lately of Great Danes mating with Toy Poodles.

And I was informed that's wrong because ring species formed closed loops. But I'm not sure what that means.

I didn't see that the geographic arrangement was so important to the concept. Thanks.

Google let me down. I didn't find anything on ring species and cichlids. I did find something on adaptive radiation and Lake Tanganyika cichlids though.

Lol and I found an final exam from a 100-level college course on evolution.

Thanks. I like these close to home examples. I have a fishtank with African Cichlids about 5 feet from me right now.
