I've often heard of this happening. If they were my dogs I'd ask what products the groomers used and suggest they used something else. Even better, of course, is to groom them yourself (it's much more satisfying, and very good for bonding and strengthening your relationship) and avoid it happening again. :)
If he hasn't calmed down by now you may well have to bath her yourself in a mild shampoo to get rid of the smell that's winding him up.
