Dog Food 101: Breaking Down Grains and Gluten Free Diets
Dog food has changed radically over the last decade. In years gone by, we fed our dogs on scraps from the table and that seemed fine.
These days, feeding our dogs has become a science of discovery.
Initially, a few brands of kibble came onto the market and soon became a convenient and cost effective way to feed our dogs.
As manufacturers realized the opportunity in the pet food market, a plethora of brands sprung onto the shelves of pet stores, giving us choice as to what we fed our dogs.
In the early days, the majority of the bagged kibble was grain based and that was acceptable at the time.
We are often asked the question of whether a dog needs grains or, indeed, if grains have health benefits for dogs.
To explain, dogs are omnivores, which mean they can eat meat, fruit and vegetables, all things sourced in the wild.
Ingredients like maize, soy, barley and wheat create bulk to dog food and are inexpensive. However, a dog’s digestion is not equipped to break down and metabolize complex carbohydrates and cereal grains.
Whilst many dogs appear to do okay with a diet containing grain, most will thrive on nutrition with higher meat content.
Veterinarians and food manufacturers are discovering that grain free dog food can be problematic for some dogs, causing allergies and other health problems, which we will discuss later in this article.
What is grain free dog food?
Grain free dog food contains NO grains. With no grains added, dog food manufacturers replace the bulking ingredients with a higher content of meat, fruit, potatoes or other vegetables.
What grains are in dog food?
The most common grains in dog food are:
Does grain free mean carb free?
A grain free diet does not necessarily mean it is carb free. It depends on what ingredients have replaced the standard grains.
Some manufacturers replace with healthy carbohydrates like sweet potato or ordinary potatoes, which are carbs.
Meats are protein, needed in a healthy diet for dogs.
Is grain free pet food more natural?
Dogs, though not strictly carnivores, will scavenge any food but it is more natural for them to eat meat, vegetables and fruit, which they could scavenge in the wild.
Thus, a grain free dog food is more natural than one that contains grains.
What is gluten free dog food?
To answer this question, let us explain that gluten is a protein found in certain grains, notably barley, wheat and rye.
Gluten free dog food would contain no grains whatsoever to fit the description of gluten free.
Is gluten free dog food a fad?
Gluten free dog food has certainly become popular over the last few years, but for good reason.
Dogs do not digest grains particularly well, so a diet that contains gluten can cause a range of health issues from allergies to digestive problems.
Are there any benefits of going gluten free?
With any mammal, good digestion is the key to optimum health. If your dog has a compromised digestive system, this can create all sorts of health problems.
A gluten free diet ensures that the food has no grains in it.
Of course, you still need to check what ingredients are in the food of your choice.
Most common are root vegetables, which digest easily, and a range of fruit and vegetables.
Normally, a grain free dog food will contain more meat content than a food that has grains in it.
Grain free vs gluten free dog food
Ideally, they are the same. As gluten is a protein found in grains, then a gluten free diet should contain no grains and a grain free diet should contain no gluten.
How to know if your dog needs grain free or gluten free dog food?
If your dog is presenting any health issues like allergies, upset tummy, skin conditions, itching or ear infections, the first thing to check are the ingredients in his current food.
Your veterinarian can do an allergy test to identify the causes of your dog’s allergic reactions.
A quick tip that might help you to understand what is or isn’t a good kibble
The ingredients on the dog food bag list the largest percentage of ingredient first, down to the smallest percentage of ingredient.
If maize is the first ingredient listed on the bag, know that this kibble contains more maize than any other ingredient. For a dog with health issues, this could be a concern.
Our advice is to look for a grain free dog food that has meat listed as the first ingredient and with the highest percentage of all of the ingredients in the food.
Does my dog need grain free?
An ideal dog food is grain free or limited grain. Some dogs appear to have no issues with a diet containing grain, but look at their stool on a daily basis.
A diet higher in meat will produce a smaller stool and with less smell. Dogs fed on a diet containing grains can experience loose stools, flatulence or diarrhea.
Does my dog need gluten free?
The answer to this is the same as if your dog needs grain free. The health benefits of having a gluten free diet are as great as a diet with no grain.
What about dog food allergies?
As we mentioned earlier, if your dog’s digestion is not functioning 100% there may be some health issues.
Typical problems seen with a diet containing gluten or grain are:-
Dog breeds at a higher risk for food allergies
Some dog breeds seem to be predisposed to higher risks of food allergies. This is typically prevalent in pedigree dogs, but does not rule out cross breed dogs.
This is not a conclusive list.
One of our writing staff is an ex dog groomer with seven years’ experience. She reported that out of the hundreds of dogs she groomed, the dog that had the worst skin conditions, stemming from food allergies, was the West Highland white terrier.
Is grain free to way to go for my dog?
We may be biased in our opinions, but we would answer that yes, grain free is the best diet for your dog.
Most food allergies start from around the age of five months, so starting your puppy on a puppy grain free diet can positively influence his long-term health and well-being.
Where did grain free dog food come from?
By nature, dogs are scavengers. With their highly developed sense of smell, they can sniff out food easily.
A dog will eat pretty much anything edible like corn, grains, vegetables, fruit and, of course, meat. When dogs first became associated with man, they were fed on whatever was available, mostly food scraps and leftovers.
From around WW2, the first sealed bags of kibble became available, mass-produced for the pet food market.
As the public got used to the convenience of bagged dog food, new manufacturers rushed to produce the next best-selling kibble.
Today, as you search for a new food for your dog, you face the dilemma of choosing from a HUGE selection of kibble, all promising that they are the best for your dog.
What are the benefits of grain free dog food?
As we have mentioned earlier in the article, the greatest benefit is improved digestion, which can influence the immune system, skin condition and general health.
Effective digestion is at the heart of good health.
Potentially, the main benefits are:-
That said, not all allergies are food related. Some dogs have allergies to other things like air pollutants.
However, diet is always a good place to start when you are trying to identify the cause of health issues. Consultation with your veterinarian can identify the cause of allergies.
Tips for going grain free
As with any change in your dog’s diet, do not switch to the new food immediately.
Keep feeding his original food, but replace with half a handful of the new food for a day or two.
Then gradually add more of the new food and less of the old food.
The reason for this is that your dog could get an upset tummy as his digestion is not used to the new food.
This change over process should only take about a week.
During this period, observe your dog closely. Watch out for any tummy issues, changes in behaviour or vomiting.
If you are at all worried, stop feeding the new food and check with your veterinarian for advice.
Low carb misconceptions
Gluten free or grain free does not equal a low carb diet. Always check the packaging to see what the ingredients are.
Manufacturers will often use sweet potato, potatoes, tapioca, rice or green peas, all of which are moderate to high carbohydrate content.
Should puppies eat grain free food?
Start your puppy as you mean to go on. Your new puppy may have an upset tummy for a few days when he first arrives at your home.
This may be partly down to the stress of his new environment. He does not know you and may be missing his siblings.
If you have bought him from a good breeder, they will have given you a week or more of his usual food. Ask the breeder what the food is so that you can do your research on it.
You must purchase a dog food specifically for puppies – at this stage of life, a puppy has different needs to an adult dog.
If you are choosing gluten free or grain free food, make certain that you buy puppy specific. Most manufacturers have this option.
Then decide if you want to put him on a gluten free or grain free dog food. Potentially, this may reduce potential health issues once he has settled at home with you.
Allergies usually begin at around five months old, so generally within the first two months of you bringing him home.
Source good quality gluten free or grain free dog food and look for one with meat at the main ingredient.
Before switching your dog to a grain free diet
We would always advise discussing this with your veterinarian before you consider changing your dog’s diet to grain free.
Although we have explained the benefits and it may be something that you feel strongly about, it is wise to have your dog checked first to confirm that there are no underlying issues.
If your dog already has issues and you aren’t sure about the food you are currently feeding him, you can get an allergy test done with the vet who can tell you what the likely causes are for the allergies.
Doesn’t my dog need fiber?
A diet that is low in fiber can create loose stools. A good quality grain free dog food will have sufficient fiber for your dog. If in doubt, consult with your veterinarian.
