Outlook and ongoing care
With successful treatment, your dog’s outlook is excellent. As long as they stay on treatment, they can live a long, happy life without symptoms.
How long does thyroid medicine take to work?
Your dog should seem happier and more energetic within a couple of weeks. They may lose more fur to begin with but don’t worry, this is normal, it should start to regrow within 4-6 weeks. They should be looking slimmer and healthier within 3 months and be back to normal within 6 months.
Your dog will need regular vet checks, and you will need to monitor for any new symptoms. Your vet may perform repeat blood tests to ensure your dog’s thyroid hormones are staying at the right level.
