Since my mom is a groomer I've been taking Sophia since she we got her at 12 weeks. I know it sounds a little crazy, but she's 17 weeks now and she has already taken a liking to getting a bath and everything! The younger they are when they first start going, the easier it is for the pup to adjust. I would suggest waiting till your furbaby has all necessarily puppy shots just for his safety. Find a trusting groomer and explain to them you're a little nervous, it's his first time going.. they should be very understanding!! Very often my mom lets first time parents hang around and watch their furbaby get their first bath
