The body only needs support on the bottom between the legs and under the chin. My slicer tries to support the back of the head and where the fur starts but it's not needed. I removed the supports from there and printed fine.

The horn is separate for easier printing. The best way i found to print is in this orientation, seen on the 3rd picture. But if you find a better way go with that. You have to glue the horn in place.

Cheers!
