Have a basic first aid kit for your dog in a container clearly marked Dog First Aid Kit or something similar, it is also a good idea to have your veterinarians telephone number clearly written on the container in an emergency or panic situation it can take time to find the relevant number.

 Inside the container should be:-

Tape to hold or to fasten on bandages

Bandages of varying sizes (the conforming ones are best as they mould to the area you are going to dress) and always be sure that any bandage used is not applied too tightly.

Sterile dressing pads of varying sizes (do not use lint or cotton wool)

Sodium Bicarbonate (for Bee Stings)

Vinegar (for Wasp Stings)

Scissors (the blunt or rounded ended ones are the best)

Tweezers (in case of easily removed splinters etc) 

Plastic gloves to protect yourself and your dog against infection

A Notebook and Pen is also a good idea to make notes of the dogs condition

An eye bath and some Optrex  or Sterile Water (for washing away grass seeds etc from the eye)

It is a good idea to carry the first aid kit with you when travelling with your dog or out walking, keep the box easily accessible in the home emergencies can happen anywhere. Be Prepared.

If you do a lot of travelling with your dog/dogs it is also a good idea to have a sign on your car window to say that you have dogs on board. and even better if you can add Dogs On Board In case of emergency please call veterinarian (vet fees guaranteed). A point to mention at this time is that whenever travelling your dog should be restrained either by a car dog harness, or they should travel in a dog box or cage, for their own safety and for the safety of their owners. I know we don't like to think about accidents whilst travelling, but they do happen.
