I am so grateful to you for advising me not to put Cubay through the ordeal of heartworm treatment. He tested negative on his annual check up - Yay! His bloodwork was irregular with liver enzymes and something else I can't remember so they are retesting him in six months.
Otherwise he continues to be a good friend to Robbie. Brandy is so old and deaf, she barely knows he is around. He is such a sweet boy and always so polite. Thanks for giving me the gift of adopting him.
