14 Common Health Problems Every Dog Parent Should Know
02. Ear Infections

Ear infections in dogs are usually caused by too much yeast or bacteria. These infections can lead to your dog shaking their head and scratching at their ears. You might see discharge or debris in the ears, and they can have an unpleasant smell.
Ear infections can be itchy or painful, and if not treated, they can cause significant harm. If your dog shows signs of an ear infection for more than a couple of days, it's best to visit the vet. These infections may also occur alongside skin problems and can be linked to allergies.
