Wisconsin Wildlife Safety Tips

Here are some tips to fulfill that:

- If you’re with a dog, ensure it stays on a leash and closes beside you. Wild animals tend to get irritated by dogs easily.
- Don’t try to surprise a mother with her child or try to intimidate an animal. Most wildlife ferociously defends their young. Don’t try to play with or carry their young.
