Should I go to the emergency vet?

Run the standard playbook, keep notes on how your animal responds, and change course when the notes say to.

How much will treatment cost?

Smell from the mouth, ears, skin, or a wet tail fold is usually an exam of that site, plus a cytology swab. Dental films and a cleaning under anesthesia are a different estimate from an ear flush. Ask which end of the dog the quote covers.

Can I treat this at home?

Wipe a dirty fold and smell the ears, the mouth, and the rear end so you can tell the clinic where it is strongest. A yeasty ear or a rotten tooth will not clear with a scented shampoo. Skip essential oils on the skin.
