Maybe. Elkhounds and Keeshonds do look similar. Perhaps there's a cross breed in there that is limiting the coat length.The first word that came to mind was Keeshond............not sure of the spelling, sorry.
That is the healthiest, darkest color, curliest tailed coyote I've ever seen.Uuuum....I think that's a Coyote and you better let him back outside ! : )
I see some Norwegian Elkhound! My doggie is part Elkhound I've also seen a lot of pics of both purebred and elkhound mixes. A lot of them seem to be mixed with GSD or husky so it's quite possible even likely, on there being some GSD and/or husky.
Perhaps Akita and something else?
