Actually let me go see what they're called.
OK they're called Perfect Coat (that's the brand name) puppy bath wipes. You don't need to get the puppy kind, that's just what I bought. And this is what it says at the bottom
•safely removes dirt, dander and tough pet odors
•enriched with moisturizing conditioners to leave coat healthy and shiny
•alcohol-free formula is mild enough for every day use
•premium cloth material is durable, yet gentle on skin
I'm sure there are other things you could use, this is just what the trainer said would be a good idea and we've liked them.
