first aid kit for 2 dogs (choco pie + chopper)

My two dogs are very different. Choco Pie is a small, crazy girl who eats everything on the floor. Chopper is a Border Collie and she is more careful, but she runs into the fence sometimes. So our first aid kit has to work for both. What we keep at home: gauze, saline, a roll of vet wrap, a small tube of antiseptic, tweezers for ticks, a thermometer and a cold pack for heat. In the car we keep a towel, a bottle of water and a copy of their vaccine cards. For Choco Pie we added a plastic cone because she licks everything. Check the kit every 3 months. The gauze expired last year and I did not notice until I needed it. Nothing big happened, but I felt bad.
