The weather is getting very warm, especially for wolves that don’t shed their undercoat until late May or June. Many people ask why they shed so late. There’s no real data to answer that question, but May and early June are the worst season black flies, a small gnat that is know for an intense bite. Maybe over time, wolves were selected for the later shed. Since the humans are all scratching and the wolves aren’t bothered by the black flies, it seems like a relevant theory. In this week’s image, Grizzer is posturing over Maya and she willingly submits. There are a few indications that the testosterone hormone is still strong in these males.
