Ernie our 3.5 year old Miniature Schnauzer's blood work came back, and he has a high CK. It was high last year also. His vet says it's nothing to worry about but it must be a clue. I don 't have the actual blood work but last year it was 484 U/L H. (Penny had her blood work today.) So I will be making appointments shortly! Thank you!
