I wanted to again thank Dr. Kerpsack for the amazing gift of saving my puppy's life. Lincoln was diagnosed with a liver shunt after surgery when he was 13 weeks old. That was 5 years ago. Lincoln has lived a great life, blessed many people and has enriched my life beyond words. Lincoln was certified CGC at 10mths, agility at a year, has done print ad work, a Time Warner spot on Austin Pets and won Austin's first hippie hound contest!... There isn't a day that I don't think of Dr. Kerpsack and his ability to save our precious pet. I am forever grateful.
