We go camping with our dogs pretty frequently. Depending on how cold it gets you might want to also bring some blankets or even an old sleeping bag for the dog.
Some of my other suggestions are pretty obvious, so I moved this one way up:
- Get a leash-light thing. In the off chance that the dog gets off the leash or take off at night, you don't want to be stumbling around searching for them with your flashlight - it's not fun. Put a light on that sucker.
- Use a harness and keep the dog on a leash at all times. And make sure to actually secure the other end of that leash to something else.
- Bring lots of water and be prepared to take your dog everywhere you go.
- Make sure they have their proper tags. And likewise, make sure they're up to date on flea/tick medication and other shots.
- Once darkness rolls around and we have the fire going, the dog will be pretty happy to just snooze until sunup, whether it's next to you around a campfire or kept secure inside your tent. My dogs are usually pretty glad to sleep on top of my air mattress in the tent while I'm enjoying the fire, but it gets a little cramped once I head to bed, so I like having something else they can sleep on.
Educate yourself on whether dogs are even allowed where you are going. For example, there are no dogs allowed most wilderness areas in national parks. That is they are often not allowed on trails.
This can save you a lot of trouble down the road.
While dogs are allowed in the camping areas most national parks. ational forests seldom prohibit dogs.
We've been to a majority of wilderness areas and national parks in west coast states and they pretty much all prohibit dogs anywhere but parking lots and camping sites. Some places allow dogs on select trails, but they are usually shorter trails around campgrounds. National forests and most state parks are good with dogs as long as they are leashed.
