About a year ago she had been having some vomiting and regurgitating ongoing issues. I checked a small mass on her flank and diagnosed an MCT which I removed.

The one on HR treated with Stelfonta and when we checked we couldn&#39;t find one one on the left stifle. Gone. This was about 3 months ago. The owner is under instructions to very closely monitor the dog.&nbsp;</p><div style="clear:both;"></div>
