Dogs should never be allowed to sit on your lap to look out of a car window. Consider a doggie booster seat instead. They will have great viewable and be safely restrained at the same time. An unrestrained dog is a projectile!

Distraction toys such as a Kong can provide additional hours of fun if you stuff it with Ultramix sweet potato or pumpkin puree and freeze the toy until the puree is solid. Be sure to give the stuffed Kong to your dog outside or somewhere where you won’t mind cleaning up the mess – if he doesn’t lick up everything for you! Peanut butter is another great option.
