Plant-based vs Insect-based dog food

We applaud all the new companies looking at alternative protein sources to feed our production animals and our pets. We have chosen not to include insect-based dog food diets in our list of sustainable foods that we recommend for dogs, for the reasons listed below:

Are Insect-Based Diets Hypoallergenic?

For dogs needing an animal protein free diet, the only one that is truly free of all animal proteins, is a vegan dog food diet. Yora insect-based dog food lists chondroitin as one of its ingredients which is sourced primarily from avian cartilage.

That is why dogs with an intolerance to chicken protein (a common intolerance in dogs advised to eat chicken and rice when their intestines are at their most inflammatory); will react to Yora due to the presence of the chondroitin.

Dogs with the most common allergen that we see – an allergy to house dust mites, have shown to react to the chitin in dog food that uses insect-based foods.

Dogs with an intolerance to genetically modified corn, could react to insect protein made from companies such as Protix that feed their grubs with cornmeal.

Are Insect-Based Diets Truly Palatable?

When we think of the smell of fly larvae, think of what maggots in your bin on a very hot summer’s day smell like…..then yes, the palatability for dogs is good as dogs are drawn to strong smells (even if we find them very offensive!)

It is the owner that has to choose the food however and keep the food in their pockets on walks and this is where plant-based foods with their distinctive herby smells of basil and oregano really top the popularity for owners!

What of the safety of Insect-based vs Plant-based dog foods?

When considering what the fly larvae used in insect-based foods are fed which is not going to be freshly sourced vegetable matter, but rather the waste matter to make it a cost-effective way to produce the insect protein; these waste materials come with the added concerns of mycotoxins and bacteria.

All insect-based protein used in pet food has to undergo stringent ‘detoxification’ prior to being added to the food to ensure that there are no toxicities to dogs and cats that come especially from mycotoxins. These are not present in plant-based foods sourced from fresh ingredients.

Which is more sustainable – insect-based or plant-based pet food?

It was while attending the Glasgow Small Animal Pet Food Symposium in March 2024, that the true cost of insect-based protein was made clear.

Entocycle (now listed on the stock exchange) attended the Symposium to talk about insect-based pet proteins after Sustainable Pet Food Association and raw vet . They are one of the biggest producers of fly larvae protein for the pet food market. What a surprise after they showed us the dangers of the use of meat in pet food accounting for so much global biodiversity loss due to intensive farming….but went on to tell us that the fly larvae intensively farmed by them for their protein, were fed from palm kernels from the palm oil industry!

Just as the use of animal byproducts in pet food encourages the production of more animals to be intensively farmed as a price is put onto every part of the animal; so too will the use of palm kernels encourage yet more extensive palm oil production and even further dangerous biodiversity loss.

What is more cost-effective – Insect Protein or Plant Protein Dog Food?

Considering that the insect-based protein has to undergo ‘purification’ of all bacteria and mycotoxins, as well as be processed to ensure not just safety for pets but also palatability, there is a difference in price with many of the insect-based products being more expensive than their plant-based options due to extra electricity needs.
