  • Cook mushrooms in chicken broth for the added flavor
  • Use a small amount of olive oil to sauté mushrooms

Don’t forget, some types of mushrooms are poisonous to dogs, so keep a close eye on your pooch when you’re out and about in wooded areas. And if by any chance your dog manages to eat a wild mushroom, call poison control or take it to the vet right away!
