I am driving home for Thanksgiving in a few weeks with my 4 mo English Pointer puppy. We will be in the car for 8 hours each day. She is a pretty high energy dog but usually does fine in the car but most car rides are 30 minutes or less. We have done an hour long drive a few times and she was fine. She sometimes has a problem because she gets bored very easily and dislikes playing with toys unless someone is playing with her, so turns to chewing on the car. What can I do to prevent boredom? She will chew on cows ears, bully sticks and other animal parts in the car but I don't give her more than one a day and it usually only takes her an hour or two to finish one. I've thought about giving her kongs stuffed with her kibble and frozen but am not sure if that will just mean kibble all over my car (we buckle her up in the back seat of my sedan). She has never been car sick, even on the 10 hour drive home from picking her up at the breeder's house, so I've not been concerned with that. I plan to stop at dog parks and State/National parks along the way to let her get some energy out, but there is the possibility that a park might not work out due to other dogs that might not get along with her. I have a hard time tiring her out as she gets bored with games with me long before she runs out of energy. Does anyone have any ideas?
