Well I just came inside with Tripp, I had him on the back porch in my lap and I was rocking on the wooden swing. He was very calm and relaxed but kept licking his lips and then threw up some food. He did this the other day and threw up phlem and I didn't think anything about the swing, just that he had an upset stomach. When he has just eaten he throws up in the car. Is he just really motion sick and has a sensitive stomach or should I be worried about something else
? Thanks for the help
