Bathing a dog in an acrylic or plastic bath will result in the bath getting scratched - we know - we've got one

We now use one of those horrid non-slip mats for bathing Brude
I had to laugh at the description of the dobermutt's showers - occsaionally we do this to Brude, but the door's a bi-fold one, so he can't escape
I've said it somewhere before, but unless you're going to take your labrador hunting and shooting, then leave him/her in a kennel, the 'natural weatherproofness' thing doesn't have to apply
There are show judges who trot out this little gem about other breeds, but still bath their own dogs regularly
Personally, I'm with Shihtzumad on this one..... Brude isn't allowed on the bed when he gets past his bath-by date, so a regular bath gives us a happy beagle (even if he does look cross when you mention the word

)
