When Rodders came back in from the garden it looked as though he had been making mud pies with his chin and his beard was covered! I have taken a photo and must try to remember to come back and add it later.
The muddy puppy also wanted up for a fuss. While he was in my arms I started to comb through his legs and face but couldn't get under his chin. I put him on the floor on a snuggle fleece and managed to get through the worst of it, he wasn't too happy though as I had to tug a bit in places.
ETA Not a great photo, but you get the idea!
