Garlic and onion have numerous medicinal properties Among which we must highlight the following:

Can I give garlic and onion to my dog?

To answer this question, let me start with a practical situation. One day for lunch I decided to invite my dog ​​and put some sauteed potatoes with eggs and onions in her feeder. Then I remembered the most widespread myth in canine nutrition "the onion is toxic" and I went into a state of hysteria, in a relentless search for information I realized that I had used a medium onion to prepare approximately 3 plates of food and that the toxic dose for my dog ​​(a labrador) was 3 medium onions. I breathed and watched calmly as my pet continued to enjoy an optimal state of health.

If we are going to give a yorkshire a plate of homemade food cooked with onion, are we going to use a whole onion in an exclusive preparation for our dog? Probably not, and here is the key.

So that a dog can (because it is not a safe fact) get intoxicated with onion, you should consume 0.5% of your body weight in onions, and that is an excessive amount that has no place in a balanced diet for dogs.

If you want to give your dog foods containing onion, you can give 2 to 3 tablespoons of these without any problem. Also, are you going to give him food prepared with onion every day? Do not suffer from onion poisoning in dogs if you use this vegetable reasonably.

As for garlic, our fear must be even less, since it contains less sulfur substances that can be toxic. Thus, a dog can eat 1 to 2 cloves of garlic daily, depending on their weight, it is more, in this food we find the best home remedy to deworm them.
