I carry a cut kit that includes a tube of antibac, teflon coated pads, tape and a desposable razor ... I also carry a small pack of butterflys ..... I carry this stuff in an old canvas dog boot that will protect an injured foot for the trip home. I teach all my dogs to drink from a regular .5L spring water bottle and I bring as much for him as I bring for me. When I drink, he drinks.(mine is spring water .... his is a tap refil)
