Very good question

It’s hard for me to say this is a working kennel, as I newer did see any of there dogs But I think they pass the tests you are interested in >>> Kennel Dakmat http://dakmat.wolfdog.cz/anstart.html

If you was looking for Trailing dogs, maybe kennel Zlata Palz would be a better choice ? >>> http://www.wolfdog.org/eng/dbase/o233.html

Water rescue dog kennel ??? ??? >>> http://www.wolfdog.org/eng/dbase/o1224.html

Of course there are more working kennels and I hope they will be added by somebody that knows more than me and did see them live

But I think you are to look after a litter from two good working dog
And that litter might not be in a working dog kennel at all...

But at least this is a start hope the experts will fill in the rest
