Bono was 6 when he was diagnosed with Endocardiosis (an unforgiving and terminal form of heart disease, which degrades the valves of the heart) Although he'd had a heart murmur since he was around 3. When I asked his vet how long he would live, she told me "He'll be lucky if he reaches 9-years-old".
After a few days of crying and cuddling Bono, I decided that I was going to help Bono fight this horrible disease, that I was going to bankrupt myself if I had to to pay for the highly expensive but available treatment, which would at best slow down the deterioration of Bono's heart. There is no cure for Endocardiosis.
The average life expectancy of the Cavalier King Charles Spaniel is 10-years-old. And so, naively, I made a target. I said he was going to live till he was at least 10, to which the vet said, "No; don't set targets. Just enjoy him". But I felt that if I didn't, that would be the same as giving up. I wasn't prepared to do that.
I paid for every treatment available even though financially I was struggling and had to make huge sacrifices. I even postponed my wedding to my fiancé for this treatment, I threatened to resign if my employer didn't increase my wages, we cancelled our holiday abroad.
Bono saw the specialist cardiologist vet at least once every 2 weeks, sometimes weekly, receiving ultrasounds, xrays ...
Many nights when Bono was coughing and feeling unwell, I stayed up all night with him, then dragged myself off to work in the mornings. I had to get up at 4am to give him medication every morning anyway, and then encourage him to have breakfast. He was such a fussy eater, and insisted on being spoon fed. You know when someone loves their dog when they are sitting on the kitchen floor at 4 in the morning every morning, spooning organic dog food into their mouths, and giving them ham if they eat it up like a good boy.

All to no avail, Bono went into Congestive Heart Failure and 6 months later, sitting in an oxygen tank at the vets, his heart gave up at the tender age of 8 years, 6 months, and 23 days ...
There was no chance he would have made it till today. It's possible I may even have euthanised him when the quality of his life went. But he had been keeping fine up until a fortnight before he died ... It all happened very suddenly.
Anyway, I'm rambling. I'd like to send a message out there to all those people who mean to purchase a Cavalier King Charles puppy or breed them. Please do not breed them till they are at least 3 years old and are showing no signs of a heart murmur, and please do not buy a puppy from a breeder whose parents are under 3 years old, or who have a heart murmur. If you do, you're only breeding heart disease, the killer which took my boy's life so prematurely.
Happy Birthday, Bono. Miss you. x
