What causes an enlarged heart? I have a new baby. She is actually 11 weeks old. Plays actively. Eats regularly. Has gained about 2 oz. a week. She's perfect. No coughing. No heart murmur. BUt has has a bit of a cold. Took her to vet and with an xray found a slightly enlarged heart , nemic, and an infection. Any thoughts. We are having the xrays fedexed to an expert. BUt it feels like forever to hear back. Vet said heart problems generally have a murmur. Maybe at 1.9 lbs she needs to grow into her heart. BUt I am just about to die with worry. Any thoughts or past experience. Thanks!!! |
