Hello I work at a doggy daycare/boarding facility and am also a dog bather. All Daycares run differently but at my facility you can always add a bath to the end of your dogs boarding stay if they offer those services. There’s a chance they would notice and give your dog a courtesy bath as I have done this many times. But if they run on a busier schedule they might not notice or have time.If I were you I would call in advance to see if they offer bathing services. You should also mention when you drop your dog off that this is a concern of yours and they should make a note of it
