I posted about the puppy with the 3 murmur. I have spent the last few days contacting vets and researching. It seems overwhelming that 1-2 murmurs are accepted and not worried about much at all. # is obviously on the borderline, but like Jennifer said, flow rate is good info to know. I just found out the pup's flow rate is 1.5. If she told me that the first time we talked, I forgot about it, because I doubt I would have been so worried. It seems like under 2.4 is acceptable. It's like our blood pressure, the higher it is, the worse off. I doubt VERY much that 2/5 meant 2-5, that is almost the entire spectrum. (0-6) I have come across more people than I thought, that have dogs with murmurs. It is more common than I realized, that is for sure. Most seem to make sure the dog gets a VERY good food, and not overheat. Hope that helps some. I am still researching, whether I get the privilage of owning the little guy, or for future knowledge, just in case.
