Thank all of you for your replies. I definitely agree with the part about the breeder not standing by her puppy. I just couldn't believe it. I also plan to do what I can for my sweet Maggie but I am a little stressed financially at the moment. I have a few of my own medical bills from an
accident and also I've had a vacation planned for next month since last year. I am going to do the ultrasound next month and see what the vet suggest and see if she thinks it's necessary to see a cardiologist. Maybe it will be better than I think. I'm hoping for the best. I will keep you updated for sure. Thanks again for all the advice
