No, I haven't ever seen it, truthfully. One thing I did find that was good and didn't bother me - or the dogs, was the old LOC (Liquid Organic Cleaner) put out by AmWay. I just hated dealing with the AmWay people, though. [shudders] I was tickled to find out about the Neem based flea shampoos, since they killed the fleas and didn't cause any adverse reactions AND supported Rain Forest based products.
In truth, I don't do dog baths on a regular basis - only when they stink in a way that can't be brushed off with the dried cow muck, lol! It's usually a spur of the moment thing and they get the benefit of my organic shampoos and conditioners! My little beauty queens, rofl! It's no wonder they're an egocentric pair of princesses. Move over, Paris and Nicole! And my girls actually do real work, too!
Bimmer is so fastidious about his hygiene that he rarely needs any emergency bathing, just good brushings and an occasional bath. He's a real pleasure; he's got the most beautiful pelt - he shines and shimmers in the least bit of sunshine.
