Pesto is a sauce that is made from fresh herbs, olive oil, Parmesan cheese or cottage cheese, and pine nuts. The traditional pesto recipe includes basil, which is an anti-inflammatory herb, but you can also use other types of fresh herbs such as parsley or cilantro. Pesto can be used on pasta, pizza, chicken, fish, and vegetables. It is a very versatile sauce that can be used in many dishes. For humans, pesto has health benefits. However, this does not mean that dogs can eat human pesto all they want. Human pesto is high in fat like peanut butter, and it can cause digestive problems in dogs if they eat too much of it. Pesto can also contain garlic and onions, which are both toxic to dogs. Onion is especially harmful to dogs because it can attack a dog’s red blood cells and cause anemia. Garlic can also be harmful to dogs, but it is not as toxic as onion. If your dog were to eat garlic, they would likely experience gastrointestinal upset, such as vomiting and diarrhea. So, before you mix human pesto with dog food, think again!
