RE: XTRA Large form?
The measurements we as taxidermists speak of are a circumference just below the ears, the head/neck juncture, but on the meat, NOT over the skin and hair. Also, that second measurement is 3 inches down the back of the neck, while the tape stays in the same place in the front. Theres plenty of large forms available, and like Alex said, we routinely alter for larger size.
