A fixed formula pet food simply means that every time a new batch is made it contains exactly the same ingredients. Simply put, each time you buy your pup’s food there are no major differences. Now you may be asking why this matters? Or what is the best fixed formula pet food that you can feed your dog? Let’s dive in and take a look at how we can keep your pup happy and healthy….


Why fixed formula is pawsome!

You may have noticed that when you change your dog’s diet a little their toilet’s are not the most pleasant. This is because they are not used to digesting the new food. This could even be triggered by different batches of the same food, which is why fixed formula pet food is super important! For dogs with gastrointestinal sensitivity, a variation of ingredients can cause gastrointestinal upset. So a good thing to look for when choosing a pet food is a declaration that the food is made to a fixed formula, which is common in healthy vegetarian food for dogs. 


Over in the meat dog food industry….

The same cannot be said for many meat-based foods which are made to an “open formula”. This is because the main protein sources can vary greatly between batches, depending on availability and price. In these foods, one batch may contain mainly poultry meat, the next mainly another source e.g. pork. Your pup may have trouble digesting this causing gastrointestinal upset.


Good news!

Did you know that dogs are omnivores (1)? They have 30 copies of the AMY2B gene responsible for digesting plant-based foods (2). This means healthy vegetarian food for dogs are not only digestible but super healthy for them too. Multiple health benefits have been reported for dogs on plant-based diets such as improved weight control, decreased incidence of cancer, decreased infections, diabetes regression and better skin/coat quality and odour (3). Ready for a happy healthy pup? Make the switch to plant-based dog food.

FAQs

But aren’t dog’s carnivores?

Dogs are in fact nutritional omnivores as demonstrated by a robust scientific study published in the reputable journal Nature (1,2) in which it was shown that they have 30 copies of the AMY2B gene responsible for digesting plant-based foods.

They have also evolved relatively long intestines (21) (almost as long as humans) and relatively flat surfaces on their molars (31, 22) which they use for digesting and chewing a whole range of foods.

The common misconception that dogs are carnivores probably arises from the fact that they are classified in the order Carnivora but so are plenty of other species like bears, skunks, racoons who are omnivores and even the giant panda who thrives on a plant-based diet (20).

Is plant protein digestible to dogs?

Absolutely yes, studies which have looked at how much protein dogs can absorb from plant-based and fungi-based foods like soya and yeast demonstrated over 75% digestibility which is on par with meat-based foods (23, 24, 34, 35 & 25).

Both these protein sources also contain all 10 essential amino acids (36, 37) that dogs need to thrive.

Isn't there too much fibre in plant-based food?

The average amount of fibre in a commercial dog food diet is between 2-4%. omni’s plant-powered recipe has a fibre content of 3% which is on par with meat- based diets.

In our survey with over 200 dog owners, 100% reported that their dog’s stool consistency was either ‘normal’ or ‘perfect’ and there were no reports of any digestive upsets (data on file).

Can I mix omni with other meat-based diets?

We are proud that our recipes are nutritionally complete and so include everything your dog needs to thrive. This means omni can be fed as a sole ration. We also fully support a 'flexitarian approach' like meat free lunches or using omni as a mixer.

Every little helps to bring some of the health and environmental benefits of plant-power to meal times. Mixing omni with meat/fish will help to add variety into your dog’s diet whilst adding in healthy ingredients with a relatively low carbon footprint.

Can plant-based food provide the essential fatty acids dogs need?

All the essential fats and oils that dogs need, including omegas 3 and 6 are found in a variety of both meat and plant-based foods (31, 28).

omni’s recipe is rich in plant-based sources of these nutrients so your dog will get all the essentials they need.

I hear a lot about feeding raw meat, isn’t that better?

Feeding raw meat to dogs has become a very popular trend in recent years, but most vets will warn against this practise. This is because the cooking process is vital to help kill off dangerous bacteria like E coli, Salmonella and Campylobacter (9) that have necessitated several food recalls from the market and caused serious illness and even death in both dogs and their owners (40, 41, & 42).

There are also several worms and parasites that are only killed off when raw meat is cooked. Dogs are dogs, not wolves and thanks to their domestication over thousands of years, thankfully don’t need to hunt to get their grub nor do they need to eat raw meat, it's just not worth the risk.
