Worried my dog has cushings

[Notsurewheretoturn]

9 year old chow. Healthy and beautiful. However she's lost a bit of hair from her tail. I took her for a senior health check and her liver enzymes are raised? Vet wanted to leave for 4 weeks then re test
She's slightly overweight, drinking, weeing and pooing okay. Generally well. I've bloody gone on Google now and I'm panicking.

I've had a dog with Cushing's disease. We followed vet's advice and managed the disease well. Please don't worry.

My thirteen and a half year old Irish Setter was diagnosed nearly three years ago. She has a very strict low fat diet and regular check ups. She’s doing really well. Although have to say vet care isn’t cheap.

She's not drinking or peeing alot. Her wee is amber coloured. She's lazy but always has been. Bit worried but the vet said we can re test in a month. He didn't mention cushing.
