I'm afraid Camden has never grown out of it, she's 4yrs old.
We have tried ginger, medication from the vet, homeopathic & she still throws up! She's as quiet as a church mouse and lays down! In that way she rides the best out of the three, but she just throws up!
Once in awhile we get lucky and she won't get sick, but that is more the exception!
I sympathize with you!
