I can imagine how fast he stopped, lol!
Well, there seem to be two choices. You can continue on the porch when it's cold, using hot water, working fast, then bringing him into the warm house. I used to blow dry even my super short-furred dogs when it was cold. And, even when they were bathed inside but it was winter.
Or, there's always the tub/shower...
Maybe if you don't run the water, but use the same containers as you do on the porch in the tub he will tolerate it?
I know that it's not as easy for you, but I can't think of a third option.
Love All Life, Thank You For Posting! :)
