My Dog Ate Flour- Now What?

It’s easy to spill some flour on the ground while baking or cooking. Even just quickly leaving your ingredients and finding your dog all over them can happen to anyone with a curious dog.

Can My Dog Eat Flour?

Eating flour in small quantities should be no problem for your dog. Flour is not toxic to dogs. Depending on how much your dog ate and the size of your dog, he or she could want to drink a lot of water to compensate for the amount of flour they ate. Since dogs don’t usually eat flour there could be some throwing up or loose stool as well as gas. As long as your dog seems and acts fine there should be nothing to worry about.

Eating A Lot Of Flour At Once

If you own a small dog and you suspect that they ate a lot of flour you should make sure that they drink plenty of water to make sure the flour passes through. Eating a lot of dry flour at once could possibly lead to constipation so be sure to observe your dog for a few days. If your dog starts to seem in pain, starts whining or you notice that they haven’t been able to poop, I would take the dog to a vet to be sure that everything is fine.

Digesting White Flour and Gluten Intolerance

White flour consists of easy carbohydrates for your dog to digest. During digestion, the carbohydrates are turned into glucose which (depending on how much your dog ate) are a lot of empty calories.

Some dogs, like humans, can suffer from gluten intolerance. This means that they aren’t able to digest gluten which is present in flour and other grains. You can see symptoms of gluten intolerance in your dog starting from when your dog reaches 6-7 months. Symptoms that you can observe after feeding your dog treats containing flour can be diarrhea, they can lose weight, not have such a healthy coat as healthy dogs and generally look more sickly.

Which Breeds Can Have Gluten Intolerance And How Is It Tested?

Gluten Intolerance isn’t specific to one particular dog breed but can be seen in any dog, although it has been documented more often in Irish Setters and Soft Coated Wheaten Terriers.

You can take your dog to a vet and then can do a variety of tests to figure out if your dog has it but that is not necessarily the best way to find out. Getting a lot of tests done at the vet, which can include blood and urine tests can be costly for you and stressful for your pooch. I think the better way to see if your dog is affected is to completely eradicate gluten products from your dog’s diet and observe your dog during this time period. You can remove gluten products for a good month and if your dog had been having a reaction to gluten products, you should see weight gain and all the other symptoms should start to fade away. To figure out if it was really the gluten that was the problem, reintroduce gluten products into your dog’s diet and see if the symptoms return.

There is really no need to get your dog tested by a specialist, I would only suggest going to your vet if the symptoms and your dog’s conditions don’t change through at all by changing their diet.

Treating Gluten Intolerance/ Gluten-Free Diet

Gluten Intolerance is treated by keeping your dog a gluten-free diet. Grains that don’t contain gluten include rice, quinoa, buckwheat, amaranth and others. Make sure that your dog only eats treats containing these grains and avoid treats that contain wheat (in all its varieties), barley, rye and oats. If you don’t want to be reading all the ingredients of dog treats in the store you can also just make dog treats yourself.


Eating a small amount of flour is not dangerous for your dog. If you are suspecting that your dog could have a gluten intolerance after eating flour, I would suggest changing their diet and to see if the symptoms leave and your dog gets better. Gluten intolerance can easily be avoided by keeping your dog on a diet that does not include grains containing gluten. You can also easily start making dog treats yourself if that’s something you’d like to try.
