Summer is almost here and I am in the process (as part of spring cleaning) of going through my first aid kit, getting rid of expired meds, replacing items we have used, and adding new suggestions from friends and family. The kit we carry is pretty big, and useful for animals and people in our travels. It has everything from bug repellant to band aids, an antibiotic creme, benadryl.... I keep a checklist on the lid of the kit, which is a good sized tupperware bin. I am just wondering what is your most used first aid item for your dogs, bullmastiff lovers?
