How to track your dog's hypothyroidism for your vet
Last reviewed 11 June 2026 · a 4-minute read for owners
Note your dog's energy level, any change in weight or appetite, how the coat and skin look (thinning, dryness, dullness), and whether they're seeking warmth more than usual. These changes are gradual, so a dated log is what shows your vet how your dog is responding over the weeks rather than on a single day.
What to note each time
- Energy levelNormal, a bit low, or very low.
- Weight or appetite changeAnything you've noticed — gaining, losing, hungrier, or less interested.
- Coat and skinThinning, dryness, dullness, or other changes to the coat or skin.
- Cold sensitivityNo change, or seeking warmth more than usual.
Why your vet wants this, not your memory
Hypothyroidism is followed on how energy, weight, and coat respond over time alongside blood results. Those shifts are slow and easy to misjudge from memory. A dated log lets your vet see whether your dog is picking up as expected and line that up with the testing.
Common questions
How soon should I expect to see changes?
That varies, and your vet will guide you. A log is useful exactly because it captures gradual change you might not notice day to day.
What coat changes are worth noting?
Thinning, dryness, dullness, or patches of hair loss are common things owners track. Describe what you see and let your vet interpret it.
Does a log replace blood tests?
No. It works alongside the testing your vet schedules and makes those appointments more useful by showing the day-to-day picture.
What's the easiest way to keep an energy and coat log?
Whatever you'll keep up with. A digital log captures the date for you and lets you share the whole record with your vet without rewriting it. Taile is a free way to do this.
