Been a while but I have been busy doing some add ons to crews.
These dogs were remarkably easy to base... if you keep some sprue on their feet and press these excess parts in a greenstuff base. Let them cure overnight with some support and you are done, I really don't see any other way to get them based properly. I feel (and see online) this is problematic for a lot of people, damn you wyrd!!!
Quite an impressive Hamelin crew...
