Not for us.
We don't get too much snow here, so I don't have to worry about ice balls. We get rain, but if I trim his legs so the hair isn't hanging on his feet, that keeps him mostly clean.
He has long fluffy hair (especially on his legs) all year round, and I love it! Though his body got a close trim last summer, and I think this summer/spring he'll be in a continental... lol. If not, a nice German trim for summer. I want to take him swimming a lot this summer, so he'll probably be in a closer or more manageable trim. That's really the only difference. He CAN have close trims in the winter, but I looove his long fluffy hair. He does get really hot in the summer, and I don't think I'm ready to fluff dry 3+ inches of hair every time he goes swimming lol.
