I am SO GLAD you took him for bloodwork for a wellness exam.
The above you are saying (Amox and liver support supplement) was very similar to the course the normal vet took with my boy
who had CAH. He looked completely healthy and normal, just had some evaluated values.
I hate to say this, but need to get right to the point: Drago may not have any outward signs on the physical exam, but I would not rely on that by any means
with CAH. My male had been seen less than 2 months before he was diagnosed [with CAH] by Specialists for his heart/cardio echo check and they did see anything on the physical exams that was a cause for concern as far as his liver.
My male was big, strong, looked very healthy as far as his coat and outward physical appearance was great, could and wanted to still run laps around the yard and never got tired, still wanted to go on walks, play, be goofy and happy, eat tons, etc. and yet he died within a few months, even with aggressive treatment. His only outward sign was drinking some more water than usual.
My boy declined very fast with CAH, way too fast, so fast. It presented just like you say Drago's did with the blood test value. Please have him take a bile acid test. I would also do an ultrasound. I would be aggressive with this Tracy. Those tests are not evasive and can help him live a longer and healthier life, in the case this isn't just a fluke or infection. I wouldn't mess around or wait based on what I saw happen with my personal soulmate dog.
I miss him so bad. I hope for Drago's sake his bile acid test comes back good and so does the ultrasound. Will be thinking of you guys. I know he is your special guy!
