Anyway, here's my online first aid list. It's mostly for at home:
1st Aid Kit
But, from that you can get a first aid kit for the van, and a smaller kit to carry, if you like.
I like to begin with information. This could be for you, should something happen and you need to call someone, or something for another person, should you not be able to tell them who to call about your dog.
Put them in something water-resistant, such as a Ziploc baggie, and label it with a big red and white sticker that says something like, In Case of Emergency - Addresses, Phone #'s, and Medical Info.
Have the addresses and phone numbers of:
An Alternate Vet
Your Preferred Emergency Hospital
A good friend or family member's phone #.
Pet Poison Control Center
His Medical History
List of Medications that he takes
Photos of your dog on your phone, and physical photos with your information on the back, as well as your vet's information. Think missing posters, only smaller. You want to have enough to hand out to shops where you last saw your dog, etc. In a Ziploc is good.
I suggest getting self-adhesive labels, typing the information once, then printing out however many labels that you need.
A good First Aid Book.
I place problems that might be encountered while out in only a few catagories:
1 - A dog eating something bad.
2 - A dog being stung or bitten by something poisonous, or that they personally are allergic to. Think wasps and snakes.
3 - Something getting stuck, such as in the pad of their foot, inside of their mouth, or eye. Or, a badly broken nail. Think glass, thorn, or fishhook.
4 - An injury which includes bleeding or broken bones. Maybe something falls and hits him, or perhaps it involves a domestic or wild animal.
5 - The dog getting loose and chasing something, or just having their collar/harness fail, but not going anywhere.
5 - Or, weather related. Heat stroke, for example.
To that end, I like to have out with us, in the car:
An extra collar and leash.
Salt or Ipecac
Something that will cut through his/her collar.
Needle Nose Plyers.
Venom Remover. (There's only one that I would trust.)
Kelly's and Suture connected to a curved needle, and something to Numb with.
Ziplocs for trash or samples.
A wrap of some type, such as Vetwrap.
Towel and Washcloth
Man's tie, narrow variety - look at a thrift shop/Goodwill.
Penlight or small flashlight.
Natural or Prescription Tranquilizer or Bach's Rescue Remedy
I hope that this helps, though I'm sure to have forgotten something. Let me know if you have any questions.
Love All Life, Thank You For Posting! :)
