Whether you're hiking or hunting, spending time outdoors can also be an opportunity to spend time with man's best friend. Obedience training is a must, but so is planning ahead. You'll need to pack for his needs as well as your own. There's no reason your dog can't carry his own luggage. And the most important item in his pack will be his own first aid kits.
You can make your own. Here's what you'll need. First, the essentials: a blanket, your vet's phone number... gauze bandage, which can double as a tourniquet ...first aid tape, gauze sponges, q-tips, non-stick telfa pads, saline solution, tweezers or forceps, and blunt-end scissors.
When you're in the field, you'll need more: styptic pencil to stop bleeding, topical wound disinfectant, antibiotic ointment, benadryl, buffered aspirin (never give a dog tylenol or ibuprofen. Both are toxic), pepto bismol tablets, new skin liquid bandage for patching abrasions on pads, syrup of ipecac, and wire cutters. Even the best dog can bite when he's in pain, so remember you can use the gauze bandage to make a muzzle to use while you're examining the injury or moving an injured dog.
Most field injuries like lacerations of ears, pads or tail tips, torn claw, or shallow wounds can be treated on site, with a possible follow-up with your vet. But if your dog breaks a bone, gets bitten by a snake, or gets foxtails in his nose or ears, you might want to cut your trip short and seek professional care.
