The truth is after much searching on the net, it seems there is much confliction when it comes to advice, some experts say that it is beneficial, boosting the immune system, and fights infection, but most are warning that it can cause damage to the red blood cells, which can cause anemia and even death, but I think what we need to look at is the dosage.
Vetbase.co.uk advises....."Onions and garlic, along with similar plants contain chemicals called organosulfoxides, such chemicals are readily absorbed through the gut when the plant is eaten, and in animals they, or their metabolites, can then cause oxidative damage to the animal's red blood cells. This is often serious enough to cause the destruction of the red cells - a process known as haemolysis. This can result in haemolytic anaemia if large numbers of red cells are destroyed. Haemolytic anaemia is a serious condition.Poisoning usually results from pets consuming a large amount of onion or garlic product in one go, or after repeatedly eating smaller amounts at regular or frequent intervals. The quantities of onions consumed does not need to be particularly large; for example, onion poisoning can occur after the consumption of as little as 150g in a 10kg dog."
But I'm still confused.. I google 'Dog Biscuit Recipes' and they are still telling me to add garlic,in fact I have a few doggie treat books, with 80% of the recipes using garlic..
My conclusion is that I will not be using it..
