The vet called yesterday and confirmed that yes, Jack has hypothyroidism. It’s been causing lethargy and weight gain mostly, but also some flaky/scaly ears and a few instances of unsteady walking. The gastrointestinal issues that prompted me to take him to the vet aren’t a typical symptom but the vet said she couldn’t rule out the possibility that they were related. He’ll be on a twice-daily pill for the rest of his life, but it’s small and relatively inexpensive. He’s already had two doses and is perking up quite a bit. It makes me feel bad, wondering how long he’s been dealing with this without us noticing. I just thought he was getting lazy as he got older. It’s a relief to have a clear answer, even if it does mean having two dogs with chronic conditions!
The other good news is that I finished a sock yesterday. I’d already finished one green sock from my new sock yarn, but before I started the second I needed to make a quick purple sock. And it really was quick!
Now I’m back to the green. And when I have one solid green pair and one solid purple pair, I want to do purple with green contrast bits!

I’m glad you have an answer for Jack! It’s never easy second-guessing yourself with pet issues like that, but I hope you realize that you’re doing a great job with your puppers. And the purple sock looks great!
Thank you, I’m trying! 🙂
Glad you have an answer for Jack, and it’s a relatively easy treatment! Your sock looks great 🙂
Nice purple sock! We had a cat with hypothyroidism. The medicine made so much difference. Glad you have an answer for Jack!
Glad to hear that!
Aw I’m so glad now you know what’s going on with Jack!
Yay I’m glad you got an answer for Jack, and that he’s feeling better already!
Aw, Jack! Well, now that you know what he is dealing with, maybe he can get some relief. Don’t torture yourself with thinking about how long he may have been suffering; he is going to improve from this point on and that is a good thing. Really cute sock!
Thank you so much! He’s definitely feeling a lot better already!
What a good boy! Glad he’s feeling better
