So, Sully is 7 months old. He has had no signs of anything wrong with his heart. I had ladies over last night for BUNCO. At one point when we were all sitting there socializing and eating, Sully started to cough and kinda gag. It lasted about 15 seconds. Does this mean he has early MVD or am I just being over protective? If my Labrador had done it, I wouldn't have thought twice. Just super paranoid with my little baby. Thoughts????
