A couple of other thoughts: My investigation into Laser Therapy indicated that only the Class IV or Class V laser have good efficacy. So you might want to check what your vet is using.

There are other investigative techniques that might be less invasive than a liver biopsy that dependent on the clinical profile of your dog, might be best to do first.

It is one of the reasons why I suggest that read and consider seriously contacting Dr Tobias - at least she might or her office might be able to refer to the best/most experienced specialist closest to you.

And I can tell you that if it were me, I'd definitely postpone any spay, until after her liver problem is firmly diagnosed and treatment has shown a whole better clinical picture.
