Do any self serve car wash owners offer a pet wash?
Debra & others.
We have had our 2 room natural light Lexan clear walls & ceiling pet wash since about October 2009. Number wise ... indoor dogs are the primary visitors-clients. Of course their master-owners have something to say about that decision too. It is pretty rare to see a cat &/or a miniature horse but it has happened. We have learned that pet owners can be very fussy about their pets.
Marketing it can be tricky it seems ... that is why "word of mouth referrals" possibly are the most important. To get a thumbs up from William Pitzer (the forum founder) when he was in town was somewhat of a highlight back in in the fall of 2010. I see the link he posted on the pet wash category within the forum seems to not work anymore. Going down the page on this new link shows the the still relevant video:

Not everyone would do it over again ... we would ... it was & continues to be worthwhile.
Tom Hoffman has some with his self service car washes.
