Tips for taking 2 dogs on long car ride?

What I do is when I go on a long trip with my family and we bring our dog we don't feed (it is okay to give them some(a portion of what you would normally give them) water) them the morning of the trip just to prevent them from being motion sick. I would also cover your backseat or where ever they will be with blankets and keep a few extra. I would stop periodically, such as whenever you may stop to pick up food/gas and just walk them you pretty much want them to have nothing in their system. Also when you stop give them some water (a little fore thought here helps bring a shallow cup so your dogs noses can fit in it and also a bottle or two of water). Finally once you get to your destination after they are settled in feed them what you normally would. You can also talk to your vet on pills you might give a dog before hand(stomach settler, Anxiety pill, that type of thing). Also if your really worried about your dogs, I found that one of my dogs used to enjoy being on the floor of the car during the car drive. Also it is okay for a dog to whimper but leaving them in the back is really the best thing for them. Another thing is you should bring along leather wipes and paper towels, they are dogs if something happens it is best to be prepared. If you do chose to sedate, talk to your vet and ask about the risks, it is all dependent upon what your vets feels in the way of medication.
