Thanks, I will pickup some SAM-E at the store today, I had no idea what dose! I hope Pete has a comfortable time with you, you are doing everything to keep him happy.
My friend's mastif-dobie mix has very high liver enzymes, she is 10 and otherwise looks great. She is slowing down, sleeps a lot but has good appetite, etc., he opted for no more tests (at her age, he would not put her through any treatments other than meds). She loved the liver-cleansing diet, is back on regular now and taking Sam-e; like you, he is just hoping for some good quality time with an older beloved dog.
Hugs to Pete!
