Rukka Microlite Bathrobe...

...Perfect for keeping Sprocket dry and the van clean, especially after a Sunday morning spent playing in tidal mud-banks and fields full of cow pats and clover leafs. This bathrobe is easy to put on your dog, just slip their head through, (there’s a hole for the lead to go through it needed) and then wrap the side flaps around and Velcro them together keeping the back in place, and the belly too. One dry dog, and one cleaner vehicle.
