Dog breeds, Wild Dogs and Their Kin

Question
Hello. I have some questions about dog breeds and wild dogs.

I've heard the term coydog used, but what is a coydog?
Are there any domestic-wild hybrid breeds of dogs that are related to foxes, wolves, coyotes, jackals, dingos, and other wild dogs?
Are there any species of wild dogs that are brought into captivity and bred as pets?
Are there any new experimental and established dog breeds that have been created recently, and within the last decade?
Please let me know. Thank you.
Sincerely,
Mr. Jason Goldman

Answer
Jason, I am sorry I'm not going to be of much help to you. I have never heard of the term "coydog". The only hybreds I am aware of are the wolf hybreds. People usually mix them with a Malamute and sell as pets..however, I would never personally own one. They are very unpredictable as they are a wild animal. Other then that...I really don't know anything as far as wild dogs go. Sorry.
