Digger, regarding your dog the easiest thing to do from what I understand given what you say you want is to download an stl or obj or fff file into Blender. I understand that it's possible to do. https://www.google.com/search?q=3d+printable+husky+dog&rlz=1C1ZCEB_enUS807US807&tbm=isch&tbo=u&source=univ&sa=X&ved=2ahUKEwiXq93TtfPeAhXrlOAKHWdRDbsQsAR6BAgEEAE&biw=1405&bih=713#imgrc=Vu3G-kCJXdKMTM:
If all you want to do is to print a model and paint, why reinvent the wheel? If you have a 3D printer just download and print through Cura, or Slice3R (free) or Simplify. Good luck. I have a couple of dogs I miss as well and several cats.
