I can't take Prince with me as he gets really upset when in the car -- terrible pooping all over. I have used his crate, and this does not help. If I hold him when someone else drives, he just about tears me apart with his tromping and stomping. I have used "thunder shirts' and anti anxiety OTC pills with no relief. The odor is terrible worse than normal "poop". The vet does not want to give him meds for cars; "Zande" how do you allow your pups to "punish Mom"?
