At Dogs On The Run®, our Care Team frequently hears concerns from families whose dogs suddenly won’t stop shaking their heads. While an occasional shake is perfectly normal, repeated or persistent head shaking is often a sign that something is irritating the ears, from trapped moisture and allergies to infections that require veterinary care. Because our professionals observe pets in real home environments, we’re often able to spot early warning signs and alert families before minor discomfort turns into a more serious issue. When in doubt, ongoing head shaking should always be evaluated by a veterinarian to ensure your dog stays comfortable, healthy, and pain-free.
