I get a load given to me each week by my butcher. They are approximately 12 inches x 6 inches (tapering to a sort of point). I would think for a Westie you could divide into about 4 portions. I usually halve the ones I get with a pair of good kitchen scissors, cutting between the ribs. I then put the portions into freezer bags and put in the freezer. I get them out to thaw the night before they are to be fed in the morning.
Do they have much meat on them or have the been stripped? If they've been stripped I'd give him a little raw meat as well for that feed, if they are meaty feed as is.
