Can Dogs Eat Blueberries? Are Blueberries Good For Dogs?

Can Dogs Eat Blueberries?

If you’ve ever been snacking on a handful of blueberries and wondered whether it’s okay to toss one to your dog, you’re in luck. Blueberries are one of the safest and most nutritious fruits you can share with your pup, and most dogs take to them quickly.

That said, as with any food outside of your dog’s regular diet, there are a few things worth knowing before you make blueberries a regular part of their routine.

Are Blueberries Good for Dogs?

Blueberries are often described as a superfood, and for good reason. They’re small but packed with nutrients that can benefit both humans and dogs. Here’s a closer look at what makes them so valuable:

• Antioxidants: Perhaps the most well-known benefit of blueberries. They contain high levels of antioxidants, particularly anthocyanins, which give blueberries their distinctive deep blue color. Antioxidants help protect the body’s cells from damage caused by free radicals, which can contribute to aging and disease over time. This is just as relevant for dogs as it is for humans, and research has suggested that antioxidant-rich diets may support cognitive health in older dogs in particular.
• Vitamin C: Supports immune function, helps reduce inflammation, and plays a role in collagen production, which keeps skin, joints, and connective tissue healthy.
• Vitamin K: Important for healthy blood clotting and plays a role in bone metabolism.
• Manganese: Supports bone development and helps the body process proteins and carbohydrates. It also plays a role in the production of enzymes that support overall metabolic health.
• Fiber: Supports healthy digestion and helps regulate bowel movements. The fiber in blueberries is gentle and well tolerated by most dogs.
• Phytochemicals: Naturally occurring plant compounds that have been associated with a range of health benefits, including reduced inflammation and a lower risk of certain chronic diseases.

Blueberries are also relatively low in calories and sugar compared to many other fruits, which makes them one of the more diet-friendly treat options available. For dogs who need to watch their weight, blueberries are a much better choice than a lot of the commercial treats.

Downsides of Blueberries

Blueberries are one of the more forgiving fruits when it comes to dogs, but there are still a few things to be mindful of.

The fiber content, while beneficial in the right amounts, can cause loose stools or digestive upset if your dog eats too many in one sitting. This is especially true for dogs who aren’t used to eating fruit. Starting with a small amount and building up gradually will help you avoid any unwanted digestive consequences.

Although blueberries are relatively low in sugar compared to other fruits, they do still contain natural sugars. For dogs with diabetes or conditions that require careful blood sugar management, it’s worth checking with your vet before adding blueberries to their diet.

Blueberries are small, which makes them a low choking risk for most dogs. However, for very small dogs or dogs who tend to gulp their food without chewing, it’s worth halving them before serving just to be safe.

Frozen Blueberries for Dogs

Yes, frozen blueberries are safe for dogs and are actually a popular treat option, particularly during warmer months. The texture changes slightly when frozen, becoming a little firmer and more satisfying to chew for many dogs. Just make sure you’re offering plain frozen blueberries with no added sugar, syrup, or flavoring.

Dried Blueberries for Dogs

Dried blueberries are not toxic to dogs, but they’re much higher in sugar than fresh or frozen blueberries since the water content has been removed and the natural sugars become more concentrated. Many commercially dried blueberries also contain added sugar, which makes them even less suitable for dogs.

If you want to offer blueberries as a treat, fresh or frozen is often the better choice. Dried blueberries should be given very sparingly, and you should always check the ingredients to make sure no sweeteners or additives have been added.

How Many Blueberries To Serve Your Dog

As with all treats, blueberries should make up no more than 10% of your dog’s daily calorie intake. Since blueberries are small and low in calories, this actually translates to a reasonable number for most dogs. As a rough guide:

• Large dogs can comfortably have around 10 blueberries at a time.
• Medium dogs do well with around 5 to 7 blueberries.
• Small dogs should have just 2 to 3 blueberries at a time.

If you’re introducing blueberries for the first time, start with just a couple and see how your dog responds before offering more. Monitor for any signs of digestive upset over the following 24 hours, and build up gradually from there.

How To Safely Serve Blueberries to Your Dog

Blueberries are one of the easiest treats to prepare because they require very little effort. Here are a few ways to serve them:

• Fresh blueberries: This form is the simplest and most straightforward option. Give them a rinse first to remove any pesticide residue or surface dirt, and serve them as a quick reward or snack.
• Frozen blueberries: These are a great warm-weather treat. You can freeze them as they are or blend them with other dog-safe ingredients like plain yogurt and freeze the mixture in an ice cube tray for a more substantial frozen treat.
• Mashed or blended blueberries: This form can be stirred into your dog’s food or spread onto a lick mat for a more enriching feeding experience.
• Mixed with other dog-safe fruits: Blueberries can go great with other fruits like banana or watermelon. Just be mindful of total portion sizes when combining multiple fruits.

Always avoid blueberry products made for human consumption, such as blueberry muffins, jams, juices, or flavored snacks. These typically contain added sugar, artificial sweeteners, or other ingredients that are not suitable for dogs.

Signs Your Dog May Not Be Tolerating Blueberries Well

Most dogs handle blueberries without any issues, but it’s worth knowing what to watch for when introducing any new food. Signs that blueberries may not be agreeing with your dog include:

• Vomiting or diarrhea after eating
• Excessive gas or bloating
• Itching, hives, or skin irritation, which could suggest an allergic reaction
• Lethargy or loss of appetite

Blueberry allergies in dogs are uncommon but possible. If you notice any of the above signs, stop feeding blueberries and speak to your vet to work out whether they are the cause.

The Bottom Line On Blueberries For Dogs

Blueberries are one of the best fruits you can share with your dog. They’re nutritious, low in calories, easy to prepare, and most dogs enjoy them. Whether you’re using them as a training reward, a snack, or a topper for your dog’s regular meal, blueberries are a simple and beneficial treat option for most dogs.

As always, keep portions sensible, introduce new foods gradually, and check with your vet if you have any questions about your dog’s individual dietary needs. For a full range of treats and meals crafted with your dog’s health in mind, Spot & Tango has everything you need.

Frequently Asked Questions About Feeding Blueberries To Your Dog

Can puppies eat blueberries?

Yes, puppies can eat blueberries in small amounts. They can be a useful training treat for young dogs because they are small, low in calories, and easy to handle. As with any new food, start with a small amount and monitor how your puppy responds. Their diet should still be primarily made up of nutritionally complete puppy food.

Are blueberries safe for dogs with allergies?

Blueberries are not a common allergen in dogs, which makes them a reasonable treat option for dogs with food sensitivities. That said, any food can potentially cause a reaction in some dogs. If your dog has known allergies or a history of food sensitivities, introduce blueberries gradually and monitor closely.

Can dogs eat blueberry muffins or blueberry yogurt?

No. Blueberry muffins contain sugar, flour, butter, and potentially other ingredients like xylitol that are harmful to dogs. Blueberry-flavored yogurts often contain added sugar or artificial sweeteners. Stick to plain, fresh, or frozen blueberries, and if you want to use yogurt, choose plain unsweetened yogurt with no additives.

Do blueberries help with a dog's cognitive health?

There is some evidence to suggest that antioxidant-rich diets, including foods like blueberries, may support cognitive function in aging dogs. While blueberries alone are not a treatment for cognitive decline, they can be a useful part of a diet that supports long-term brain health. Speak to your vet if you have specific concerns about your dog’s cognitive health.

Can dogs eat wild blueberries?

Wild blueberries are safe for dogs and are actually higher in antioxidants than commercially grown varieties. The main thing to be cautious about is making sure you have correctly identified what your dog is eating, as some wild berries that resemble blueberries can be toxic. If you’re out on a walk and your dog shows interest in wild berries, it’s best to discourage eating them unless you are completely certain of what they are.

What should I do if my dog ate a large amount of blueberries?

A large quantity of blueberries is unlikely to be toxic, but it may cause significant digestive upset due to the fiber and sugar content. Monitor your dog for vomiting, diarrhea, or signs of discomfort, and contact your vet if symptoms are severe or prolonged.
