Hey Cheri, I know about dogs in the truck. I have three of them. (two at a time). Guess what, I love it and you will too. They are loyal and great company, don't mind my (bad) singing, are great security, (many times i have seen crackheads and lizards, look at my front seats and move quickly past my truck), are nice to warm up with in bed if I don't feel like idling or using the generator, and they are healthy. Healthy?? Yep, as I know you are all aware, expediting doesn't always lend itself to the best workout/eating habits. With my dogs, I use my down time to hike. We have hiked everywhere from South Texas to Alabama, Canada to Cali and West coast to east. They love it and it expends energy for them and keeps me in good shape for my age. I love ALL dogs and some people here have made excellent suggestion. Poodles are smart and feisty, and c spaniels are loyal sweet dogs. With that said, I favor medium and big dogs. I'm a fairly big guy, but truck places are rough sometimes, and I love the "back-up" of my dogs. As a female driver, that should be an important "side" benefit for you. I have a German Shepard, (almost 15 now and has been with me on the road for 9 years now after I rescued her from a shelter in N.E/ La.) Great girl, but shepards do shed, and she's big). I also had to buy a ramp for her in her golden years to get in and out. My "Chowranian", mostly chow, not quite as big at 38lbs is loyal, loving, and the BEST watch dog I've ever had. He sits at night in the driver seat in front of the curtain, scoping truck stop action with a nasty look, but isn't a chronic barker, sheds less then the shepard and only wakes me with a bark and a growl, when someone shady gets too close. Finally, I have a pit bull/lab mix, the baby of the group, a Cali rescue and the young one. Great deterrent, although he's the one likely to play with people, (he has shown flashes of a good watchdog learning from the chow). Yes, I have to brush them constantly, and vacuum the truck daily, and keep them up on all shots and health issues. (I would do that even if I didn't need to for crossings), and a couple time a year, I find out AFTER arriving at a gate, dogs aren't allowed on property. I either "schmooze" the guard or use that time to get them groomed, and I do have to use the generator or idle when I wouldn't, but for me it's worth it. So Cheri, go to the POUND, get a nice sturdy, medium, (Non-puppy), that is already "truck-broken", and that dog will love the road, and you too and make a great road adventure companion! Good luck Cheri! (PS, when the truck needs maintenance or cleaning, or I just need a night in a hotel every couple of months, (Red Roof, Motel 6, and LaQuinta all take dogs, and so do many independents nowadays)
