"The main reason I stick to the small doses of Ibuprofen is just adabtability as it just gives you a few more potions for dealing with small children. But your right the bigger dose are often a lot more conveniant (and its often annoying having to swallow a virtual pile of pills rather than just one)."
Good point on the childrens dose, I would just break the tablet in two but thats not always possible (I carry caplets not round tablets for this reason - each manufacturer of generic drugs tends to use their own shape so I choose based on the shape I want). Another answer would be to consider carrying some of each dose - I assume from the numbers of doses you carry that you are just adding the whole box to your kit. Consider adding one blister pack of each dose size rather than 2 the same. Gives more flexibility.
"Never considered the possible treatment of animals. Good point. I don't have much experience with dealing with that sort of thing so good tip with the spray, I'll have to get me one of those."
I noticed you have a spray can of powder to help clotting. This is also a good way to go on fur as adhesion of dressings can be a problem.
Which reminds me that you should consider adding either mastisol or tincture of benzoin as an adhesive to help site dressings on wet skin. Plus some cotton buds to apply.
You also put down lots of safety pins. Very useful. If you havent already though add some nappy pins (no idea what they would be called in the USA before anyone asks) very useful to have a guard over the point when you have a safety pin in an awkward dressing espicially when very cold and you dont feel the jab.
