I'm sorry to hear of this with your cocker spaniel and I'm sorry that your question wasn't answered in a timely manner. Please note that the degree of liver enzyme elevation doesn't correlate well with the severity of the underlying illness...which appears to be the case with your dog. I'm not certain what "fuzzy" implies; it usually means that the ultrasound waves had to pass through more tissue than usual as might be the case in an obese patient. Ideally, the fuzzy area should be needle biopsied under ultrasound guidance. Barring exploratory surgery, it's the only manner we have to clarify the etiology of liver enzyme increases. Be sure to recheck those test results in a week. There's always the possiblity of lab error. Please respond with further questions or concerns if you wish.
Thank you for your kind accept. I appreciate it. I can't set a follow-up in this venue so please return to our conversation - even after rating - with an update at your convenience. You can bookmark this page for ease of return.
