Those long floppy ears are endearing but they cover your dog's ear canal creating a moist warm environment that lacks air circulation.
This can cause your dog to suffer from chronic ear infections that can be difficult to cure.
Cocker spaniels and golden retrievers are just a few of the breeds that suffer from this common problem.
Notice any discharge, redness or swelling. If you suspect an ear infection, see your veterinarian for evaluation and treatment.
