Thanks for reaching out—let's unpack this. Seeing elevated ALT and AST levels in your dog's bloodwork alongside a low T4 can definitely raise some flags, so I understand your concern. Here's what might be happening: ALT and AST are enzymes that indicate liver function, whereas T4 is a measure of thyroid hormone. When T4 is low, it often suggests hypothyroidism, a common issue in dogs that can affect multiple organ systems, including the liver.
Hypothyroidism can indeed lead to elevated liver enzymes because reduced thyroid function slows metabolism, which might impact liver performance. Other symptoms of hypothyroidism include lethargy, weight gain, hair loss, and skin changes. At home, ensure your dog maintains a healthy weight and gets regular exercise, as this can help manage basic symptoms and improve overall well-being.
Keep an eye out for signs like increased lethargy, vomiting, loss of appetite, or noticeable behavior changes, as these could indicate a more serious condition needing immediate attention.
It’s important to confirm the diagnosis and explore treatment options, so I recommend booking a video consult with one of our vets on Dial A Vet. They can guide you on the next steps, including any further testing or treatments that might be necessary.
Dog has elevated ALT and AST, low T4. Could this be a thyroid issue?
Something weird just happened with Luna, and I'm honestly freaking out a bit. It's been a couple of days since her last vet visit, and they said her ALT and AST levels were elevated, plus her T4 was low. This honestly went right over my head at first, but now I'm wondering if it could be something with her thyroid? She's been kinda sluggish, not her usual playful self, and she doesn’t seem as excited about her breakfast in the mornings, which is really unlike her. I don't know if I should be really worried or if this is something other dog owners have dealt with. Our vet appointment is still a week away, and I'm just anxious. Has anyone else dealt with this? Should I be doing something in the meantime? Any advice would help ease my mind, thanks!
