If your hiking partner's middle name is Trouble (or Cuddles, or Thor, or...
), you'll want to be prepared for any scrapes your dog may wag his way into.
Fortunately, a well-stocked, standard First Aid Kit can doctor both man and beast.
There are a few items that are particularly helpful when traveling and hiking with dogs.
Consider adding the following to your travel kit, or even to your First Aid supplies at home.
Essentials For A Canine First Aid Kit

• hydrogen peroxide - to clean wounds and induce vomiting (use 1-2 Tbsp.
  )
• *styptic powder + cotton swabs - to clot blood from a torn or broken toenail
• alcohol wipes - to disinfect small wounds
• comb or brush - for removing burrs, ticks, and dirt
• muzzle - because injury makes pets unpredictable
• sterile gauze pads + *vet wrap - for wounds and wrapping limbs
• old beach towel - a stretcher for an injured dog, warmth for a pet in shock, a rag for wet paws
• baby socks or dog booties - to cover bandaged paws
• duct tape - to secure baby socks, waterproof bandages, and 101 other uses
• emergency vet number and vaccination records - in case your dog needs immediate care
• Fido's photo - in case your pet is lost

* Items available from your veterinarian and most pet supply stores.
Augmenting a basic First Aid Kit with your dog in mind requires minimal effort and upkeep, and will help ensure that every member of your family can get the "unexpected care" they need.
However, more important still is the sort of planning that ensures you'll avoid a whole host of troubles down the road.
Any time you venture out with your dog, take the time to practice good common sense.
Prevention is always the best protection for your dog's health.
Essentials for Every Dog on the Go

• a well fitted harness/collar and leash - obviously, the most effective way to keep your dog out of trouble and out of traffic
• current vacinations and a clean bill of health
• fresh drinking water for your dog - puddles and ponds and even streams can carry dangerous bacteria; if you plan on sharing water, make sure there is plenty for the both of you
• ID tags - your dog should always wear up-to-date contact information, a rabies tag, and dog license, if you're traveling far from home, add local contact information, as well (e.
  g.
  your hotel, local phone, etc.
  )
• a canine car restraint - whether it's a seat belt harness or a crate, it's worth the trouble to buckle up your pup every time, to protect everyone in your car
• poop bags - practice responsible dog ownership wherever you go, and Keep America Beautiful!
