Hi Traci

I have a husky/shep mix. I can't say my Cody has the type of odor you describe at that particular time of year. What type of smell is it? Could she be rolling in something? I know that in the spring Cody does her MAJOR shed. She has the typical husky double coat; I have to handpick out the wide fur clumps that pop out like qtips! Then, everyday, at least ten minutes of brushing. I would think that all that shed fur, if not removed quickly, would begin to take on a scent, shall we say, after getting wet, dirty etc. Try combing and brushing well every day. I HAVE to bathe Cody at least every 8 weeks; she is outdoors playing everyday. I truly don't believe that bathing every 6-8 weeks should be a problem. The act of brushing alone helps to release those essential oils you speak of. Using the proper shampoo product is, of course, very important. Ask your groomer or vet. There are some great products out there.
Good Luck to you and "Stinky" (Just kidding Nikko!!!-Hugs)
