1. She hasn't anything different to eat or go into anything.
2. Not sure of weight, small for her breed.
3. No pre-existing medical conditions
4. Been going on for about four hours but it seems to have stopped now after happening about every half hour
She is due her shots-boosters, including for kennel cough and I was concerned it was that she had picked up but she hasn't vomited for over an hour now-actually she wants to go for her walk so I,m going to take her see how it goes.
She is also overdue to come into season
