How can you feed Soy Beans to your Dog?

There are many dogs which are allergic to it. In general, dog allergies are found in protein rich foods, especially dairy like chicken, beef, soy, eggs or gluten. There are other cautions to note before going all-in and serving a nice Soy Beans to your dog.

  • Cooked Soy Beans – Never ever feed your dog a raw Soy Beans. It is not toxic per se but anything raw can be susceptible to a lot of bacteria and diseases which can upset your dog’s stomach.

  • Plain = No pain – Dog’s stomachs are not made for anything spicy or salty or even very sweet for that matter. So, while serving Soy Beans, make sure they are plain without the use of any butter, salt or any other spices

  • Mix it up – Just for the taste as soy beans are not the best on the taste scale and the dog would probably avoid it. So its better to slide it in the dog’s meal and mix it up with other foods to make it eat soy

  • Test and then taste – Always check if your dog is allergic to soy or no before feeding it. In case of not knowing it, start with a very small quantity and then gradually increase if no threats are seen

But make sure you fall for the nutritional thing and end up feeding it more of it. Stick to the recommended quantities. More Soy Beans ≠ More Love but = Bad gut health

What can happen if your dog eats an unusual amount of Soy Beans?

If your dog ate some more Soy Beans, which he probably wouldn’t because of the bad taste but yet if it does while you were getting ready for a date or enjoying a Netflix session, look out for the following symptoms of an upset stomach. You should contact your vet right away if you see –

  • Vomiting

  • Excessive licking

  • Hair loss

  • Bloating

  • Constipation

  • Abdominal pain and tenderness

  • Constipation

  • Gas

In some cases, it has also been seen to cause seizures in dogs because of the allergic reactions


While studies are yet going on whether Soy Beans are completely safe and healthy for dogs or no, the nutritional list shows that they can be very healthy and even safe for most dogs except for those with allergies. So go ahead and slide a couple pieces in the dog bowl and it will reward the dog with better health and immunity.
