Elevated ALT, low albumin, high platelets

[speever1]

Hello everyone - I have a 7 year old female spayed frenchie who was just diagnosed with high liver ALT 437, low albumin 28.2 and high platelet count 449 as well as SG urine 1.018. I took her in to the vet because she seemed to be peeing a lot, and more restless than usual at times. I had a former female frenchie who had elevated ALT at an older age and it was never discovered what the reason was - she had the ultrasound, bile tests etc and was on denamarin until she passed away. so I am wondering if it is possible that frenchies may have congential issues like shunts? Any feedback would be great.
