My dog is dizzy, drooling, and her head is shaking. What's wrong?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 2 years and 5 months old | 22 lbs

3 days ago my dog had foam coming out of her mouth while she smacked her mouth, it happened 4 times, each lasting 30 secs to a minute. A day later her eyes sometimes looked dizzy/unfocused. She has also been walking slow and she sometimes looks dizzy. The top of her head does this weird pumping thing, it goes up and down and her ears move a little. She still eats and drinks regularly.

Snow needs to see the veterinarian today. Dizziness is never normal and can indicate many things including toxin ingestion, drug exposure, an infection in the brain, brain cancer, low blood sugar, an inner ear infection and other serious reasons. A physical exam and bloodwork are needed to begin figuring out the cause and the best treatment. Other diagnostics may also be indicated.
The lip smacking may indicate nausea which has many many causes and may be related to whatever is making her feel dizzy.
A bump on her head could be many things. It could be an inflamed cyst but something like a cancerous Mast Cell Tumor can also behave the same way. Make sure to discuss all three of these things with your vet. I hope they figure things out quickly and that she gets back to normal quickly.
