About 3 or 4 years ago I had a full waterproof suit inc legs made to measure for one of my OES from a company that also made bibs etc for large breeds (I think the company was called Droolabib or something).   They also beautifully embroidered dog name / affix etc on the suits.  However I now need another one for a different dog and can't find any trace of the company so have to assume that they don't exist any more.  The standard ones I can find for sale on the internet don't fit a fully coated adult male oes as it don't want the coat so squashed that they look like the Michelin man!  Does anyone know of anywhere that might offer a similar service? It was great having one that fitted so perfectly round the body and the right leg length that didn't interfere with boots. 

Have you tried Equafleece ?
Their fleece is waterproof and I am fairly sure you can contact them with sizes and they will try to help.

Ok thanks I will speak to them,I hadn't before as I always assumed they would be too hot (as my boys are often v warm anyway due to their coat) but they will be able to tell me if that would be the case. I've used their suits on oldies who have been clipped back and loved them.  It's only for going into shows on wet days rather than normal life as I would rather walk mine in than put them in a trolley.

Equafleece coats are weather repellent but not waterproof

Clumberjack, you might be better off with one of these if your aim is to get a dog into the show ring in pristine condition
