We have a 7 month old Labrador and he is great in the car, however we have only travelled at most for about 45 minutes. So we are off on holiday and the car journey will be up to 3 hours. So we are looking for advice to make the journey as positive and comfortable as possible. For example how often would you stop, best time to travel, etc etc. We are also going on a ferry so any helpful tips there as well. Thanks
