Every so often I get a worried query from a pet owner concerned that the amount of garlic present in our products will harm their pet. My answer is always no.
Onions and garlic contain a chemical called thiosulphate. Thiosulphate can cause a condition known as Haemolytic Anaemia in dogs and cats. This is where the red blood cells weaken and burst. A dangerous condition.
The amount of onion that a dog would have to eat in order for this to happen is a single meal of 600 to 800 grams. Or a daily meal of 150 grams. Conclusion: Its probably a good idea to avoid feeding your pet onions.
On the other hand, the amount of garlic you would need to feed your pet in order to get an adverse reaction is 50 large cloves. FIFTY cloves.
Garlic is good for your pet. It will help your pet fight off disease, repel fleas and generally become more healthy. Other benefits noted by scientists include: antifungal, antibacterial, blood sugar stabiliser, digestion enhancer, heart tonic.
There is absolutely no harm in feeding a clove or two a day. There is absolutely no harm in feeding the Herbal Pet supplements.
But, if you’re a garlic farmer and you have a spare fifty cloves lying around, don’t feed them to your dog or cat. Please.
