I have a 6 month old Sheltie named Max. I bought Max from an Amish breeder. I asked him questions and saw the parents...but I guess I didnt ask the right questions. He was around 9 weeks when I bought him, 5 days later I took him to a vet for his first shots. The vet had a hard time listening to his heart and took him in the back room to listen better. She said she thought Max has an echo or possibly a small heart murmur. 2 weeks later I went to get his 2nd shots...same thing happened. She said that she cannot say for sure if it was a murmur or an echo, but if it was a murmur, then he would likely outgrow it. 4 weeks later i took him to a different vet to get his last shots and that vet said Max had a grade 6 murmur and was going to die, possibly of sudden death. I was shocked...going from possibly nothing, to a HUGE deadly murmur. I was devastated, but wanted to go back to the first vet to get a second opinion, That was on the 16th of June. the vet did in fact grade his murmur a 5/6, took an x-ray, saw the enlarged heart and fluid in the lungs and gave him 6 months to live. Max runs around like a normal healthy puppy. He gains weight, eats a lot, no labored breathing, his gums are pink, and hes getting bigger every day. I guess my question is, is there any medicine that i can give him without taking him to a cardiologist, as I just cannot afford heart surgery, and I already know that his heart is bad and I feel like an ultrasound will tell me what I already know. What signs do I need to look for other than labored breathing or coughing? He is a puppy, so he takes naps several times a day, but always loves to play and run. should i not let him do these things? What is the life span of a puppy with a grade 5/6 murmur w/o surgery? Will he get better as time goes on? As Max gets bigger, does it make more room for the enlarged heart? I am going absolutely insane, we love this little guy very much, he is the best dog we have ever had, so smart
