@Ann:
Thanks for the offer, Dan. I don't want to put you out with the mailing, but thanks for your generosity. Sorry to hear about Nika, but glad to learn about the product. I checked the Chondro-Flex site and can see it's good stuff.
At this point, we've put Noel's supplements on hold until she's completely itch free, then we'll reintroduce and try to pinpoint what might have been the trigger. I'm sure shellfish-free is the way to go. (I think my husband already ordered some online, both the canine and human formulas. We're in the same boat with Noel!)
It's no problem at all Ann. It's a waste just sitting in my cabinet.
