I stopped counting after 16. What I'm worrying about is what I feel on TOP of his back, about 6-8" in from the base of his tail. Do they grow everywhere? So far, they were all on his lower sides, upper leg area and under both front legs in what I refer to as 'armpits.' Most of the new tiny ones are all on his belly. This is the first time I've felt anything on top of his back. This is making me nervous. It's a definite lump on the top of his back.
