Have you considered a grain-free diet for your canine companion?

British dog owners have started to take pet nutrition extremely seriously over the past decade or so with a lot of information available online about pet health.

You may be accustomed to feeding your dog regular store-bought pet food without really thinking about what ingredients are used in the recipe.

If you have a dog with a food intolerance or a sensitive stomach, you may be thinking about upgrading to high-quality dog food cooked with care.

You may be surprised to learn that food allergies are responsible for approximately 10% of all allergies in dogs. Furthermore, wheat allergies make up 13% of all food allergies.

Grain is also a potential contributor to obesity in dogs. Vet Compass report that between 35%-59% of dogs in the UK are overweight or obese.

In this article, we’re going to take a look at some of the best grain-free dog food for British dogs who are looking to avoid grain in their daily diet.

What Are Grains?

Grains and cereals are commonplace in the diets of humans – and dogs. They include foods such as wheat, barley, corn, bran, oats and rice.

Healthline offer the following definition of grains:

Cereal grains (or simply grains) are small, hard and edible dry seeds that grow on grass-like plants called cereals. They are a staple food in most countries, and provide more food energy worldwide than any other food group, by far.

Grains can be an excellent source of vitamins, minerals and fiber.

You’ll probably be familiar with the term gluten-free. Amongst the human population, gluten-free diets have become more common as food companies cater to people with an intolerance to gluten.

Let’s take a look at how Petmd defines gluten on their website:

Gluten is simply the word that describes the protein portion of a carbohydrate. It is found in grains like wheat, rye and barley, but not in rice, oats, potatoes, and some other carbohydrate sources.

Just like humans, some dogs will eat a gluten-free diet to manage allergies or intolerances.

What Is Grain-Free Dog Food?

Grain-free dog food has become increasingly common over the past few years.

As the phrase suggests, grain-free dog food doesn’t contain any grains such as corn, wheat, rye and more.

Dog food companies who provide grain-free dog food will use meat, vegetables and other food sources rich in protein such as lentils.

Wheat and cereal food intolerances tend to be more common than wheat and cereal allergies.

However, some breeds such as Border Terriers, Irish Red Setters, Irish Soft Coated Wheaten Terriers and Siberian Huskies can have an inherited allergy to wheat.

If you’ve noticed that your dog struggles with poor appetite, vomiting, farting, diarrhea, weight loss or skin problems, you could try a gluten-free diet to see if you notice a difference.

Things To Consider About Grain-Free Dog Food

There are some pros and cons where grain-free dog food is concerned.

• Reduce allergy and intolerance problems – As we’ve already touched upon, grains are a food source that can trigger allergies or intolerances.

• Tackle obesity – The carbohydrates in grain can be converted to fat because your dog is taking on more energy than they can burn off.

• Easy to digest – Grain-free diets are easier to digest so you’ll have less upset tummies.

• Don’t cause spike in blood sugar – Grain-free recipes tend to use complex carbohydrates with a low glycemic index to avoid spikes in blood sugar

• Premium price – Grain-free dog food can cost more than traditional dog food given these companies use high-quality ingredients in their recipes.

• May not be suitable for all dogs – Depending on your dog’s age or other food intolerances, a grain-free diet may not be the best fit for your canine companion. You should speak to your vet for advice and guidance.

My two Alaskan Klee Kai are obsessed with Butternut Box’s meals.

They’ve gone from being picky eaters with sensitive tummies to food-motivated dogs who gobble down their meals.

I was sent some Pure samples to try and their air-dried food proved a hit with my dogs.

While I prefer to feed my mini huskies fresh dog food, I can see why Pure would be a good option for British dog owners who prefer to stick with dry food.

Pure is a great alternative to kibble, using high quality ingredients that are carefully cooked.

With no grains in their recipes, Pure could be a good option for dogs with sensitive tummies.

3) Pooch & Mutt

Pooch & Mutt are one of the leading dry dog food companies in the UK who offer dog owners the opportunity to feed a grain-free diet to their dogs thanks to their balanced and complete dry and wet food.

That’s right – you can decide whether you want to opt for kibble or wet food because Pooch & Mutt offer both options!

What’s more, Pooch & Mutt’s offerings are hypoallergenic, made with natural ingredients, vet-recommended and cater to specific needs and life stages, to ensure dogs get everything they need to live their best life.

For example, they’ve got Calm & Relaxed, Health & Digestion, Joint Care and Slim & Slender. These recipes include probiotics and prebiotics, with high meat content from a single functional protein source.

Our Verdict

Pooch & Mutt sent some samples for my Alaskan Klee Kai to try. They’re not the biggest fans of dry food as they prefer fresh meals like Butternut Box.

I loved that Pooch & Mutt provide the opportunity to get kibble targeting specific health considerations.

For instance, my male dog has separation anxiety so I opted for Calm & Relaxed, while my female dog has a sensitive tummy so I selected Health & Digestion.

They appeared to enjoy both recipes with their bowls cleaned but I didn’t notice as much mealtime excitement as fresh dog food.

However, if you want to stick with grain-free dry food, Pooch & Mutt is well worth your consideration.

4) Scrumbles

Scrumbles offer a range of dog food options that will be more familiar to British pet parents than fresh dog meals and air-dried dry food.

However, they’ve still got a hypoallergenic slant to their recipes.

Scrumbles have created some grain-free wet food options for dogs who require a grain-free diet.

Their website explains that their wet-food options include gut-friendly ingredients that don’t use common allergens such as gluten and grain. Scrumbles use slippery elm to help soothe tummies and support digestive health.

While their dry food range isn’t grain free, their wet food range gets glowing five-star reviews on their website.

If you’ve got a dog who has struggled with some digestive issues, it could be worth trying Scrumbles with your vet’s backing.
