Can your dog eat sweet potatoes? The short answer to this question is YES! Outside of scenarios where your pup may have an allergic reaction, these tubers are fine for most dogs. Sweet potatoes are sort of a wonder-food. They manage to be sufficiently potato-ey enough that you can make chips, and yet they’re classed as one of your five-a-day.
But if you’re sold on the idea of incorporating them into your dog’s diet, there are some details to think through. Sweet potato is an ingredient in many dog foods, dog chews, and dog treats. It is often included for its high fiber content and vitamins it contains. It’s also popular because it rarely causes allergic reactions. This is very important, especially for dog owners that are just testing out different dog foods for their puppies.
Sweet potato is also regularly used in homemade dog food recipes and in homemade dog treats. Most dogs can safely enjoy sweet potatoes. So how much can you feed to your pup? Will they make your dog sick? Let’s jump in and find out more!
Will They Make My Dog Sick?
However, sweet potatoes aren’t fantastic for all dogs, and some dogs should only have very small amounts. For instance, diets containing high quantities of oxalic acid derivatives (spinach, wheat germ, sweet potatoes) can contribute to oxalate crystals in urine. These can cause uncomfortable urination and blood in the urine. They can also cause bladder or urethral stones, which are painful and may require emergency surgery to remove.
These types of stones are most common in the Miniature Schnauzer, Bichon Frise, Shih Tzu, Lhasa Apso and Yorkshire Terriers. If your dog is one of these breeds, you should be careful about adding excess oxalic acid to their diet. A small amount of sweet potato now and then is unlikely to hurt.
But regularly adding extra sweet potato to a diet already high in spinach may be too much for them to handle. If your dog has previously had bladder stones removed, you should be very careful about adjusting their diet and discuss any planned changes with your vet.
In addition, every dog is different. Although rare, you may find that your dog cannot tolerate sweet potatoes. For some, it will cause an upset stomach- vomiting, diarrhea or abdominal pain. For others, it may cause a skin reaction and increased itching, which can be treated with an anti-itch dog shampoo. It is always a good idea to give your dog a small amount and watch for 24-48 hours for any adverse reactions before you progress to giving it to them regularly.
For those dogs that suffer with diabetes, you should already be aware that the diet should be extremely stable. Giving your dog sugary fruits or vegetable tidbits is likely to upset diabetes and cause it to become uncontrolled. This is especially true for sweet potatoes, which have lots of carbohydrates (there’s a reason they’re called ‘sweet!’) and a high glycemic index.
Digesting these carbs would cause a huge spike in blood sugar, which for a diabetic dog can cause serious issues. As well as additional snacks of sweet potato, diets rich in them as an ingredient should also be avoided for dogs with diabetes.
Are They Good For Dogs?
According to the USDA, sweet potato contains (per 200g) 180 calories, 41.4 grams of carbohydrate, 4 grams of protein, and 0.3 grams of fat. It also contains 6.6 grams of fiber. Sweet potatoes are also really high in beta-carotene, vitamin A, vitamin B, vitamin C, manganese and potassium- all of which are important for normal body function, such as eyesight, hair and claw growth and neurological function.
Unlike regular potatoes, sweet potatoes also contain significant amounts of antioxidants. One of the types of antioxidant in sweet potato is called anthocyanin. This has been shown to slow the growth of certain cancer cells, and mice fed sweet potato had lower rates of colon cancer. They also had less brain inflammation, better memory and increased ability to learn.
It’s not completely clear whether this effect would carry over to dogs, but there’s no doubt that sweet potatoes are a powerhouse of excellent nutrition regardless!
Sweet Potato in Dry Kibbles
It’s no surprise that sweet potato is found in a huge range of dog diets. Sweet potato is found frequently in foods marketed as limited ingredient diets for those with allergies or sensitivities. It’s commonly touted as a great way to provide carbohydrates to your dog while improving regularity.
Although sweet potato is thought to be a safe ingredient for dogs, you should be cautious about opting for a ‘boutique’ or ‘exotic’ diet, as these have been linked with the fatal heart disease Dilated Cardiomyopathy. However, many reputable brands with good safety use sweet potato successfully.
Giving Your Dog Sweet Potatoes
If this is the first time your dog has eaten sweet potato, we recommend trying them with a small amount first. Wait 24 hours to see whether they have any reactions before giving them any more. If all goes well, and they don’t develop an upset stomach, then you should be safe to continue.
It’s important to remember that treats and toppings like a sweet potato, as food or as a snack contain calories. Treats and toppings can make up to 10% of your dog’s daily dietary calories without unbalancing their main meal. You will need to account for the extra calories by removing some of their kibble at dinner time.
Over 50% of dogs are considered overweight or obese. Snacks like this can easily get forgotten when you’re trying to work out what your dog eats on a daily basis. Your local veterinary practice can do calorie calculations to tell you how many calories your dog should be eating so that you can be aware and keep their diet to the correct amount.
Alternatively, you can get in touch with a nutritionist to help you to ensure your dog’s meals are balanced. If your dog is already overweight, consider adding small amounts of sweet potato to your dog’s food, and make sure it’s a dry kibble formulated for weight loss.
Raw vs. Cooked
Dogs can eat raw sweet potato in small amounts, and will likely enjoy it as a tasty chew. It’s good for your dog’s mental health to try new foods with different textures. Just like with any other foods, dogs should be given only a small amount, and you should be cautious that any chunks aren’t big enough to cause choking.
There’s an easy way to avoid this. Give your dog long, thin, chip-like pieces that dogs can chew on but that can’t get wedged in the throat as easily as large cube-shaped pieces. If your dog is not the type to chew their food, you may need to avoid giving raw sweet potato as it can contribute to gut blockages if not chewed properly.
Make sure you aren’t loading them up on fried sweet potatoes or sweet potato french fries, as they are higher in fat content and can cause problems over time.
Can it Cure Diarrhea?
Well, that depends on the source of diarrhea and your individual dog. Sweet potato is very high in fiber, which leads to a more formed stool. This is the reason it’s included in many high-fiber formula dog foods. However, diarrhea is rarely the result of a simple lack of fiber, It’s usually caused by something else.
It could be a toxin, bacteria, or disease. Sweet potato isn’t going to cure diarrhea caused by those things, and if given to a dog that doesn’t usually them, it could make it worse by upsetting the stomach further.
However, for dogs with anal gland problems and chronic slightly-soft stools, extra fiber can help. Raw carrot is often suggested, but raw sweet potato should work as well.
Remember to adjust your dog’s diet accordingly. Just 50g of raw sweet potato is 5% of a 15kg dog’s daily calorie allowance. Meaning if they were given 50g every day, without adjusting their daily allowance of kibble, they’d soon become overweight.
