We bring our 12 year old German Shepard & it seems like we bring more stuff for her than we do for us..lol Along with all the regular dog food and medications, we make sure to have plenty of extra water, and a couple of her toys for her to chew on if she gets stressed. We removed the two thirds width section of seat bottom in the back of our wj and built a carpet covered plywood platform that extends out to the back of the front seat, that way she doesn't slide off the seat into the footwell when going over obstacles. Depending on the time of year we make sure she has something to keep her off the cold wet ground when camping. We are very conscious of extreme temperatures so she does not burn or freeze her paws, we plan on getting some protective boots for her before our next trip to Moab, its amazing how hot the sand and rocks can get. Most injuries can be handled with the same first aid kit that you carry for the humans in the vehicle. styptic powder and hydrogen peroxide solution are two additions we bring for the fur baby. We also have scanned copies of her rabies, medical certificate, and vet information on our phones in case they are requested at border crossings or by any authorities. We make sure her collar has current tags showing rabies shot, her name and our contact information, she is chipped and we have a current photo of her in case she gets lost, which is unlikely because she is always leashed, but accidents to happen. We do bring a good brush and some shampoo in case she gets into something gross, and a good evening brushing does seem to help ever so slightly with the continuous shedding, and is a good time to check for burrs, ticks and any injuries. Sometimes seems like a lot of work but she gets so excited when we start packing for a trip, she just loves it.
