So I think my newest pup Rocco gets car sick

When I picked him up yesterday he threw up on my lap like twice, then after he had a drink at Debbies house he threw up on me again in the car. I thought he was just having tummy issues from the trauma of travelling. Well this morning I am on my way to work, and I'd given the babies scrambled egg for breakfast, and I get out to put them in their strollers and I notice he's thrown up in the car seat

He hasn't had a bowel movement yet but I don't know if the throwing up is from upset tummy or car sickness. He is holding down food just fine as long as we're not in the car

If it is car sickness can he outgrow it?
