Daisy's pukes just about everytime she goes for a ride over 5 minutes. On short trips, she'll puke when she gets home but for longer trips (Mommy's shopping trips) , she'll puke in her carrier. My vet has told me many different things that can 'eliminate' the chances of puking: Dont let her look out the window when you drive,, Dont feed her before trip,, Keep her in carrier during ride.
Weird, because she always went on trips with me (in carrier) since we got her @ 3 months, and she would never puke.. It all began @ 5 months or so.
