ah, good tip. So which brands do you recommend? (that are as nice-looking as Ilse - see, there was I thinking Danish meant top waterproofing - I really like that coat, would love it in the pink. But I already have sufficient waterproofing for nipping into the shops. I'd like something better than the grubby black thing I picked up in Norfolk, and I will be walking the dog, rather than yomping over Dartmoor).[/quote]
Personally for dog-walking, I wear Jack Wolfskin or Rohan - JW is probably slightly more fitted and stylish, but the Rohan is more practical.
From Rohan, I own an Ascent jacket (£195 full price but they often have sales on) for spring-autumn and a Hillside for winter. I've had both for four years, the Hillside has never been reproofed, the Ascent has been once (I just use Nikwax) and both are absolutely fine and keep me bone dry. Keep an eye on their website as there's always offers of some sort, or look in their clearance section.
Other brands to look at would be Arc'teryx, North Face and Helly Hansen. Look for a waterproof rating of over 10,000mm - as high as possible is what you want although the maximum official rating is 20k.
