I'm in Pooland for holiday and I've had a chance to finally start backpacking, since I usually spend my life 60mi of London where "large outdoors spaces" is a thing old sages talk about. Anyways, I go for a small walk in the woods and notice it is chock full of boar tracks, as well as what I thought is likely either large stray dogs or wolves.

How worried should I be about boar or wolf attacks? Anyone from Europe carry something for self defense from wildlife?
