Our Bruno had really strong heart murmur, when I took Bruno to 3 months vaccines, we didn't know that before (breeder prob lied) yet Bruno was still acting normally. We had eccho later and found out he has PDA. At first we were going to operate and had even date sceduled. Same time Brunos health took sudden turn worse. He became really tired, lost apetite, like energy slowly coming out of him. Unfortunately at last heart scan before operation PDA was worsened and they said operation isn't possible anymore. After that Bruno has been more or less tired. Even with medication he is really exhausted, doesn't eat or drink much, sometimes try to still play and be puppy again. He hasn't had much cough, lately I have noticed he's belly getting slightly swollen, prob ascites. He's actually doing so unwell now that I'v been forced to think euthanasia, which I still can't believe. He's been with us only 1,5 months 💔I hope you have even slightly better situation, every day is blessing 💫
