Just read a wonderful article on making a first aid kit for your dog. https://healthypets.mercola.com/sites/healthypets/archive/2019/06/08/pet-first-aid-kit-list.aspx Just my experience... getting a dog to hold still to get a small thorn out of their paw with tweezers is a bit difficult. I read once that using duck tape is ideal as it is extremely sticky! It works too! Heck, I have even used it to get wood slivers or rose thorns removed from my hand!
