While I’m not sure if anti-wolf spray is a real thing, anti-bear spray certainly is. When my brother and his friend came back from a trip to Yellowstone National Park, his souvenir for me was the manual for using bear-spray which is actually quite entertaining right down to the founders “not only am I the president, but I’m also a client photos.” Also the manual stressed not to use it as a cologne or else it might actually attract bears to you.
