Timber's fight for life

Last week Thursday Timber's breathing changed. I brought him to the vet the next day and he was diagnosed with a cold or virus. He was given an antibiotic and sent home. Monday night he appeared worse so I called the vet and came in, they stated he had a bad case of pneumonia and added another antibiotic on. The next day I came home from work early in the day and helped him outaide to go potty, that's when I noticed the blood coming from his nose. My heart sank, panicked kicked in and I called the vet once again. They wanted to see him back at the clinic, so off we went. At this time they sent out a blood test to determine if my sweet baby had a clotting issue with blood in his lungs or pneumonia. I took him back home and spent another sleepless night next to his kennel watching him stand for 5,6,7 hours just panting. Last night after a bathroom steam treatment he attempted to follow me upstairs. He coughed up a large pile of mucus blood. Again called the vet, but they informed me to monitor him closely and call if anything else changed. Once again, a sleepless night of watching him stand up for 6 hours straight. The vet called me this morning (Wednesday) and informed me that they had collaborated on his tests/x-rays and believed he had heart failure. WHAT!? he's not even 11 months old.. how could my loving, happy, goofy healthy up until a few days ago puppy be in heart failure? More tests, some oxygen, an EKG, an ultrasound, some IV medication to help remove the fluid, a catheter and a consult to the University of Minnesota cardiology later, my baby is still at the vet. They believe he has 1 of 2 types of heart failure (I'll update with more specifics as I get them) but he will need an echo to determine which one. Once we have that, we will be able to pursue the possibility of treatment, if there is one. Until then, Timber will remain at the vet getting his fluid out and will begin on new medications to help with the heart failure until we can get him to Minneapolis.

He is my best friend, he is my heart and he has never met a soul on this earth who doesn't adore him. I feel his life has been shorted, he doesn't deserve this. I feel I've let him down and I'm doing everything in my power to get him back on track to live happily whatever life he has left.
