What Happens If a Puppy Takes Motion-Sickness Pills for Humans?

Human motion-sickness pills can cause overdose or allergic reactions in a puppy, and in severe cases may be fatal. If your dog gets carsick, buy dog-specific medication from a vet; it usually contains antiemetics and phenothiazines to calm and prevent vomiting, and the dog often dozes off after taking it.

Also stop feeding the dog 5-6 hours before the trip and keep the car well ventilated, letting the dog out to rest when possible.
