With all respect, dogs can go to Patagonia, Eddie Bauer, Orvis, TJMAXX, Marshalls, Nordstrom, Macys, etc. 

Those are all clothing stores.  I think REI is being unreasonable.  Considering every other sporting goods store allows them that I know of and most brands they sell actually allow dogs in their own stores. 

Dogs aren't sitting on the clothes, that's a tad unreasonable and if someone is claiming they are that allergic, how they can't stand 6 feet away from a dog in a large store? ummmm, wear a mask or stay six feet away.  No offense, but we all learned how to do this the past 2 years.  🙂
