One of our boys EVERYTIME I put him in the car he drools REALLY bad. They ride in the car all the time and never had a problem with it.Then suddenly one day Kash just started drooling everywhere. Like literally foaming from the mouth.And its the only time he does it.On occasion he even vomits in my car. They are both crate trained and he has no problem going to bed when at home but only in the car is it an issue. We had them in the crate when they were babies then let them free roam for about a month or two then Kash started drooling so we put them back in the crate to stop it from ending up covering the car in drool.Any ideas or anyone have this problem?
