In September, we told you about Kay, the bomb-sniffing military dog with heart cancer who needed surgery to make him more comfortable during his retirement with his former handler in Colorado. It took just two weeks to raise far more than the $6,000 needed for his treatment with a GoFundMe account. Now, veterinarians at the Colorado State University Veterinary Teaching Hospital have performed the surgery to remove fluid from around Kay’s heart to help extend his life. Kay, a Pit Bull and Labrador Retriever mix, served with his owner, Army Specialist Brandon Donahue, in Afghanistan. “He put his life in danger more than I did sometimes, and it just means the world that we were able to return the favor,” Donahue said.
