Dash has been acting… off.
He seemed giddy all the time - more than his usual happy self. Then he started p*eing in the house overnight, which he’s never done. He was drinking loads of water too.
I figured it was probably a UTI, so off we went to the vet - p*e sample in my pocket. But nope - urine came back clear. The vet ran some bloods just to be safe. Again, everything looked normal… except one thing: his thyroid levels were high.
The vet was stumped. Overactive thyroid? That’s a cat thing - not something you usually see in dogs. But if it does show up in dogs, there are three possible causes:
They’ve been over-medicated for an underactive thyroid (nope, not Dash).
They’re raw fed and accidentally eating meat with thyroid tissue in it (possibly - my dogs are raw fed).
They have a thyroid tumour. (gulp.)
Obviously, I hoped it was the diet. I switched it straight away. Meanwhile, the vet sent another sample off for a full thyroid panel. She’d felt something in his neck but wasn’t sure if it was anything to worry about…
Two days later, the results came back. Dash’s thyroxine level was even higher.
The vet said she wasn’t convinced diet alone could explain levels that high. And it was bugging her that she thought she’d felt something. So she got a second opinion. The second vet couldn’t feel anything. Dash had officially become a medical mystery.
We got a referral to a specialist the following week. In the meantime, we had to have some hard conversations at home. If Dash did have a tumour, the odds were high that it would be malignant (90%). But the only way to find out for sure would be a biopsy - and that carries a serious risk of catastrophic bleeding.
Treatment would involve major surgery, and possibly chemo. Dash is 11½. We made the decision not to go down that road. It felt like it would be more for our sake than his.
Still, the referral felt right. We needed to know what we were dealing with.
The specialist was amazing - but even she looked a little confused. Because thyroid tumours in dogs are usually big, gnarly things. Dash does have a tumour… but it’s small, hard to feel, and honestly? It behaves more like a cat tumour. 😂
On top of that, it’s extremely rare for a tumour to actually cause hyperthyroidism in dogs. So now Dash isn’t just unique. He’s ultra-rare. Possibly… a cat?
There’s no standard medication for hyperthyroidism in dogs, so we’re trialling a cat medication. It might help, it might not. We’re back to the vet in a week to see.
Until then, we’re focusing on just one thing:
Making sure Dash is living his absolute best life. 💛
