You can clean the ears after the bath with a cotton ball, tissue, wash cloth or Q-tip. Don’t insert the Q-tip into the dogs ear canal, it can cause damage if the dog shakes his head.
Do your best to keep water out of your dogs ears. As water collection in the ear can cause ear infections.
If your dog has droopy ears and gets water in their ears, it’s best to get a little dab of an ear drying paste or power and rub the power on the upper part of the ear to help dry them out.
