Hope your vet had some answers about Elmo for you.
We have a 14 year old boy who has a heart murmur and coughs and wheezes a bit. He is on heart meds and Lasix to help with fluid. He is checked by our vet every 3 months for updates.
We also have a 13 year old little guy who has allergies and takes a half of a Zyrtec daily which is on our vet's advice. He sneezes, coughs, snots, and has a stuffy head constantly.
Sure hope Elmo gets something that helps him. The seniors are like us humans, age brings them "trials" too!
"There’s no changing people, and we can’t even help people with whom we’re emotionally involved. Let them be, stop expecting things from people who cannot provide those things, and recognize that we can live happy, productive lives regardless of what others, even close relatives, are doing or saying."
