Ruthie's folds aren't deep. She does really well in winter with them. It's summer where I have to clean them daily cause she's always dipping her face in her pool.
Most days I think I wipe more than once... my kids are free to roam the garden pretty much as they want so they get into all kinds of dirt Especially Joey, she likes to roll in soil so she gets both wrinkle wipe and body wipe almost every day
My boys don't really have deep wrinles but I make sure what they do have is clean and dry everyday. Now butts and feet are a different story. There is always some kind of maintenance going on. lol
Both of mine have deep wrinkles so we wash wrinkles daily. That is our usual run through the house like maniacs after dinner because neither of them likes their wrinkles washed.
Yes, I wipe them everyday and his undercarriage as well. I may miss a day ever so often but as a rule its a daily routine. I use a hand towel and run it under some pretty warm water and wring it out. I cover Ace's entire face with it and wipe his face and the wrinkles and chin and ears too. Then I go over his undercarriage. He seems to like the whole ordeal. When he hears me running the water in the tub to get the towel damp he jumps on the couch and waits for me to do the job. I do touch ups in between times with baby wipes
With Vegas having severe environmental allergies it is pretty much every day, when he is outside he is like a pig sniffing in the ground. Sometimes he does get yeasty but most of the time it is just dirt since our yard is very sandy. I also wash his feet every night with witch hazel.
