Summary: Initially I was reluctant on going for an online consulting with vet, but had to avail it as it was in the middle of the night that my pug started vomiting and there were blisters all over his body and he was scratching them badly. The Vet asked me to share some pictures of the blisters and prescribed a medicine for allergy that I got from a 24x7 medical store nearby. It was some food allergy and my baby was almost normal (except those blisters that recovered the next day). He also suggested that if things dont improve in some time, I must visit a vet or call one at home. But that was not required as Ruby was perfectly normal the next day. It was really a great help as I was alone, panicked & didn't understand what to do. Thanks a lot. It's really much needed.
