Life saving heart operation for

We rescued this litttle dude. He is 11 weeks old and weights 1.8lbs. He was the runt of a litter of 4.  The family that have the mama, were told she was spayed, they were not prepared. All his sibling are doing great and adopted , his mama is getting spayed. He however has a grade 6 heart murmur and needs to see a heart specialist ASAP. Because I have so much experience with special needs dogs, I figured  i’d Be his best bet right now. The plan is to get him all the help he needs and get his little heart fixed. He will be up for adoption as soon as we can get him healthy.  If we cannot, his life expectancy is under 2 years. I have his first vet appointment scheduled for Monday. Then he will get referred to a cardiologist for a echocardiogram. After that we will know what the next step is. I will update all new information. Any amount you can donate will help. Thanks again everyone!
