New to forum...so here's our story...our 5 year old Australian Shepard lab mix (100 lbs)went from energetic puppy to old man seeming overnight. Last January we noticed his symptoms...lethargic, mopey, sad, tired, not wanting to run and play or engage, no longer jumping on bed, hungry constantly to the point of stealing off counter, garbage (which he never did) drooling, thirsty drinking constantly , peeing alot, snoring, pot belly...we went to the vet as nervous parents with the complaint of "he just ain't right". Everything checked out fine with regard to bones hips knees etc. Xrays showed nothing amiss. Urine tests (first catch in am) showed diluted urine. Bloodwork (they had him for the whole day) showed positive for cushings but they said the adrenal type. We had never heard of that before. We had ultrasound in June from prominent vet specialist who found nothing. We chalked it up as false positive results. His hair has never grown back on his belly and now I see what I suspect as that cutaneous calcinosis -scaly bumps on top of his back almost like dandruff. My question is this...if we go back to vet what next steps should I expect? If I do nothing what should I expect? We are torn not knowing and realize each situation is different. I wish there was a clear cut answer. Will meds help or hurt? Will doing nothing help or hurt? Any advice would help thanks .
