I had to take Holly to emergency vet she was flopped over and her legs were just like jerking she was choking on food and went limp and blue and not breathing it was a mess and I was a mess my children were freaking out and crying and so was I. I was whacking her on the back and trying to clear her throat and finally got it to where she finally started to breathe some but it was squeaky I knew it was still there but to the point she was getting air and started breathing again we rushed to the vet on the way to the vet she finally threw up and got the food up but raspy sounding so I wanted to make sure she did not aspirate any so we still had her checked out and they said she did not aspirate any and was overall looked healthy puppy but she does have a heart mumur. She said #3 she said all puppies are born with a mumur but usually goes away by 8 weeks she will 8 weeks on Tues. But we will have to have it recheck in a few weeks she also suggested having a cardio look at her. So now I am worried again. Anyone else have this issue with a puppy and it not be anything serious? No weight check as she said they had 2 parvo puppies in the back that had been in that area well that freaked me out she has only had 1 set of shots so far. What a night even my own children have never given me such a scare.
