We lived in KS for a few years, I don't know that I'd say it is a lot warmer than CO. The season may be longer and slightly warmer but that really shouldn't make a huge difference. Now, AK to HI that is a temperature difference. Do you have different floors where you are just noticing it more? Most dogs do shed a little all year. I vacuum everyday as fur drives me a little nuts if it becomes really noticeable. Stress will make a dog shed more so maybe the shedding is just a combination of factors. It really should even back out to what it was- perhaps shedding a little later in the season but it should go back to what it was.
