Oh, yes!! My Cavaliers haven't any ear problems, but my English Springer sure does. Spaniels are prone to them because their long ears encourage warmth and moistness inside the canal.
It's important to take precautions to keep the ears dry, especially after bathing or swimming. I put cotton loosely into the ear canals before bath time, and then use a drying agent afterwards.
A weekly cleaning is a good idea because you can stop a problem from becoming bad enough to need medication. Pet Silk has a nice mild ear cleanser that works for my crew. I'm sure you'll get other suggestions as well! Good luck and I hope your baby's ear feels better soon.
