One-and-a-half Belgians here - my long-haired one is a Belgian [Groenendael] cross, but again he needs very few baths - he prefers to bathe himself, as he is an addicted water-baby who loves to swim. He did scratch a lot on certain kibble foods including a lamb-and-rice one, but since he's been on raw and grain-free kibble, absolutely no problems. My other is a rescue Malinois, again no skin probs whatsoever. They seem to be a generally robust breed with few issues, although there can be a few exceptions, as in any breed.
I do have to say, in view of Brainless's post, that my Mali girl is an unholy roller and a walk isn't complete without finding something nasty to deck herself in... so washing down is par for the course - she is a rescue though and spent a lot of time kennelled and on her own, so I can forgive her in the main part - what I can't forgive is that she's passed the habit onto my other dog!!!
