Features to Consider for the Best Dog Iron Supplement

If your adult dogs are displaying symptoms of anemia, such as low red cell counts or poor results on a urinalysis with a vet, iron supplementation may be the solution. If you read any of my dog iron supplement reviews, you will notice that I am a stickler on reading the ingredients list and also researching them to see what they are, what they do, and how risky they may be. Here are the things I considered when deciding on what makes the best dog iron supplement:


When it comes to any dog supplement, whether they are the best dog iron supplements, dog taurine supplements, or dog potassium supplements, it is important to me that the ingredients are the highest quality and the very best for the animal possible. There is no point in buying a supplement to give your dogs if it contains something bad for them, as this would defeat the purpose. The best dog iron supplement is going to have ingredients that I trust.


The quality of a supplement depends on the ingredients and the manufacturing process. I am partial to products made by FDA-certified labs for human-grade consumption. I only buy supplements made in the USA.

I want to be certain of the quality. That is only possible for supplements made in the USA or Europe.


The taste is most important to your dogs. If they do not like the taste, they will not eat it and the product will be wasted.

Side Effects

I want my dogs to be able to tolerate supplements in their food without throwing up or having any stomach problems or reactions. Iron supplements can cause stomach upset and other digestive duress, like constipation and diarrhea. Keep an eye on your dog’s digestive habits for any changes, and consider giving them their iron supplements with food to reduce the strain on the digestive system.

Benefits of Using Dog Iron Supplements

When a dog has a bad case of anemia that is affecting their white blood cells or even their immune system, it is obvious that they are in trouble. They are lethargic and they have pale-white gums, and their red blood cell count may be low or have iron levels that are low when medical testing is done. Many abandoned dogs that arrive at the animal rescue are in this exact terrible condition. I have brought quite a few of them back from near-death based mostly on giving them proper nutrition.

One reason that I rarely have to use the best dog iron supplement is the diet that I feed my dogs chicken livers with vegetables and rice that are already full of nutrients, including lots of iron. However, I found that very sickly dogs when they first arrive at the rescue do much better when given supplements to kick start their metabolism into more vibrant recovery. It is wonderful to see them respond so rapidly when given the proper nutrition, whether it’s with an over-the-counter iron supplement or a more urgent prescription.

Precautions of Using Dog Iron Supplements

The main precautions are the potential side effects and allergic reactions, as with antioxidant supplements and other vitamins. I do not have any trouble with the product that I chose as the best dog iron supplement. Occasionally, a dog will get an upset tummy and throw up the food. Usually, this is temporary and goes away by itself, sometimes within a few hours, at most within a few days. When a dog is having stomach problems, to let their system rest, I give a bland meal of chicken broth and soft cooked rice.

Parasites like hookworms may cause stomach problems. Parasites can also be a cause of anemia, so that is something I deal with. I get rid of the parasites and then give the best dog iron supplement to help the dog rebuild its strength.

I do not like the idea of having propylene glycol in anything because I cannot control the feral cats that might wander in and steal a bit of dog food. Dogs can tolerate propylene glycol but not cats. I simply prefer never to use a product that contains propylene glycol.

Just use common sense. When trying out a new dog supplement, use a small amount mixed in with lots of food. Add a little more as your dog becomes used to eating it, and hopefully you should not have any problems.


Based on my best iron supplement for dogs reviews, my choice for the best dog iron supplement is Nutrition Strength Iron Complex For Dogs. I just love everything about the Nutrition Strength brand. The FDA-certified laboratory that makes human-grade supplements is impressive to me.

This manufacturer is so confident in its products that it gives a 365-day guarantee. I doubt if they have to refund for this product. I think it is very high quality. Nothing on the ingredients list makes me worry. I also use the second choice in my reviews of the best dog iron supplement. I use that product more for the vitamins it contains than simply the iron.

As far as taste goes, my dogs love the flavor of the Nutrition Strength brand, which is natural chicken flavor, since that is already their favorite thing to eat.
