Unfortunately this is a typical sign for a heart defect present from birth called a patent ductus arteriosus or PDA. Provided that the condition is treated before heart failure develops, the success rate associated with surgical closure is very high and the prognosis for a normal life after surgery is excellent. Sometimes, the dog may require heart medication in the future if irreversible heart damage was present before surgery. Here is some good information: http://www.acvim.org/Portals/0/PDF/Animal%20Owner%20Fact%20Sheets/Cardiology/Patent%20Ductus%20Arteriosus.pdf
