You shouldn't use them for walking on a leash, but they can wear them for tags and ID purposes.
Anyway, I wash Roxie's collar whenever I give her a bath. I take it off to bathe her, and then I wash it in the sink with the Palmolive (I think it's a nylon collar). I let it dry until the next day, and then she cannot wait to put it back on! She will hover around the counter where it's drying until I finally take it down and put it back on her!
