Garlic contains the substance N-propyl disulfid. Humans can break down this substance, but horses and dogs cannot. This substance causes the breakdown of red blood cells. A quantity of 0.2 g/kg body weight produces a detectable anaemia in a horse. So garlic is not harmless! Garlic is also associated with a lack of liver energy, which can lead to allergic skin reactions and an accumulation of waste products. This applies to pure garlic, but also to products containing garlic. With the arrival of the fly season, this is an issue to be considered and investigated.
