What Are The Harmful Effects Of Pesto In Dogs

Do not get swayed by the benefits of pesto sauce in dogs, its harmful effects in dogs outweigh the advantages:


Garlic is a member of the allium family that includes chives, onions, and leeks. Like all its fellow members, garlic contains thiosulfate, which is toxic to your four-legged friend.

Thiosulfate is a salt of thiosulphuric acid and leads to oxidative damage of your dog’s red blood cells (RBCs). This causes hemolytic anemia in your furry pal, consequently reducing his RBCs in large numbers. 

The following symptoms will be visible in your dog after consuming a lot of pesto filled with garlic:
