What will happen to my 25 lb. dog who accidentally ate a 02 mg. of levothyroxine?

If your 25 lb. dog accidentally ingested 0.02 mg (20 micrograms) of levothyroxine, it is unlikely to cause significant harm, as this dose is quite low. However, the effects can vary based on the dog's individual sensitivity and any underlying health issues. It's best to monitor your dog for any unusual symptoms such as increased thirst, restlessness, or changes in appetite. Consulting your veterinarian for advice is recommended to ensure your dog's safety.
