Open access

This opens up nearly a million hectares of countryside for people’s enjoyment in England and Wales. This symbol indicates you

I tend to use an old cheese biscuit or ice cream tub to put everything in and when putting the kit together I try to think of the order in which I would approach the problem when choosing my items.
For less severe wounds and tears you can afford to take a slightly slower approach.
If the wound is in a place where a bandage can be applied then cover it. Again a lot of us will already have some bandages, they are easily obtainable from chemists or vets and do not need to be expensive. Try get a selection: a non-adherent gauze or lint is a good first layer then aim to have a layer to pad and a layer to hold it all in place. Open weave bandages are suitable to hold padding in place but may slip if not firm. If you can get hold of some self-adhesive crepe-type dressings these should keep everything together for a while, failing that masking tape, duct tape and insulating tape are fine. For minor skin abrasions a layer of Vaseline will help protect and slow bleeding.
For the next set of items imagine different scenarios:
Nearly all of us know of a case where a dog has collapsed or gone wobbly. The finer details are still being investigated but, as many people do already, I would carry some biscuits or treats just to help keep energy levels up. DON’T give anything if surgery is likely to be needed as this may delay the anaesthetic. Be careful with chocolates as those with high cocoa solids content can be very toxic.
Even the most placid of dogs may bite when frightened or in severe pain. Never be afraid to use a muzzle either a manufactured one or a piece of bandage tied around the nose. Your fingers will be required to deal with the dog!
