Is Black Soldier Fly Larva Protein Safe for Dogs With Severe Allergies?
Is Black Soldier Fly Larva Protein Safe for Dogs With Severe Allergies? If your dog is constantly scratching, licking their paws, or dealing with one ear infection after another, you’ve probably tried a lot of diets. Maybe you’ve stood in the pet store aisle, staring at bags that all claim to be “hypoallergenic.” And now you’re hearing about black soldier fly larvae protein. Bugs? For dogs? It sounds strange, I know. But it might actually be one of the safer options for an allergic dog.
Usually. There’s one important exception, and I’ll get to that in a minute. So, is this protein from black soldier fly larva safe for dogs with severe allergies? For most dogs with allergic reactions to chicken, beef, dairy, or wheat, the answer is yes. The science to date is positive. But “most dogs” is not “every dog,” and here’s what you need to be aware of before making the change.
Is Black Soldier Fly Larva Protein Safe for Dogs With Severe Allergies?
What Is Black Soldier Fly Larvae Protein?
Its larvae the little worm-like stage before it becomes a fly are amazing at turning food waste into protein. When those larvae are dried and ground into a meal, you get a protein source that’s surprisingly close to chicken meal in quality.
On a dry matter basis, black soldier fly larvae meal has roughly 40% to 60% protein. It also has a nice amino acid profile, plus some fat, calcium, and phosphorus. One of its fatty acids, lauric acid, has natural antimicrobial properties. That’s a bonus.
But the real reason allergic dogs are getting attention? It’s not just nutrition. It’s the fact that this protein is completely new to your dog’s immune system.
Why “New” Protein Matters So Much
- Here’s how food allergies work. The immune system recognizes a particular protein as a threat. It mobilizes an attack by developing antibodies.
- The troublemakers are generally beef, chicken, dairy, wheat, lamb and soy.
- Not those backbones and breastbones the actual bacteria, insect larva and everything your dog eats. When members of one family attack, that is called cross-reactivity.
- If your dog is allergic to chicken, you’ll find they can also develop an allergy to turkey or duck their proteins look similar to the immune system. So if you move from chicken to turkey, it probably won’t help. Meanwhile, proteins that are truly chicken- or turkey-based (i.e.
- Not cross-reactive) will be all new.
- Proteins your dog has never encountered are the key to ‘hypoallergenic’ diets.
What the Research Actually Shows?
- New 2022 research in the journal of Proteomics discovered 33 potential allergens in black soldier fly larvae. The chief one is one called tropomyosin.
- If your dog has an allergy to shrimp, or dust mites, then there is the possibility that they may have a reaction to black soldier fly larvae. What about if my dog has an allergy to fish? Not necessarily. Just because your dog has a seafood allergy, doesn’t mean you’ll need to avoid feeding it to them.
- If your dog is confirmed to have a crustacean allergy, or a poorly controlled airborne allergen like dust mites, discuss with your veterinarian first.
- An allergy test and supervised food trial are the only safe options.
- What are the chances of cross-reactivity for a dog allergic to: Chicken? Very unlikely.
- Beef? Very unlikely.
- Dairy? Very unlikely.
The One Big Catch: Tropomyosin
And about that one exception I mentioned at the start. According to a 2022 paper published in Journal of Proteomics, scientists detected 33 candidate allergens in black soldier fly larvae, and the most problematic one is a protein called tropomyosin. It’s a common allergen in crustaceans like shrimp, crab, and lobster, as well as dust mites and storage mites.
- So a dog with a seafood allergy or unmanageable dust mite allergy could theoretically have a reaction to BSF as well.
- Not risky for any dog with a seafood allergy? No.
- But not worth the risk of going in without a plan.
- First, ask your veterinarian about a supervised trial diet if you have a crustacean-allergic dog or a dog with unmanaged severe dust mite allergy.
How It Compares to Other Allergy Diets
| Diet Type | How It Works | Pros | Cons |
|---|---|---|---|
| Hydrolyzed protein | Proteins are broken into pieces too small to trigger the immune system | Gold standard, very effective | Often expensive, can taste bad |
| Novel meat (kangaroo, venison) | Uses a meat the dog has never eaten | Can work well | Cross-reactivity possible, not always sustainable |
| Black soldier fly larvae | Uses an insect protein new to the immune system | Low cross-reactivity with common meats, good palatability, sustainable | Not for dogs with crustacean or severe mite allergies |
One more thing: palatability. You’d think dogs would turn their noses up at bug protein. But studies show that adding black soldier fly larvae meal at 5% to 10% actually improved how much dogs liked the food. So picky eaters may surprise you.
How to Try It Safely?
- 1. Get the diagnosis first Food allergies are difficult: Environmental allergies, parasites, and other health issues may present exactly as food allergies do. Your veterinarian needs to make sure it’s a dietary issue before you start changing your dog’s food.
- 2. Choose a complete and balanced diet: Search for a statement on the label that says it has been formulated to meet or exceed standards for your dog’s stage of life by either AAFCO or FEDIAF. Skip the “larvae” bag you just pick up off the shelf and pour in.
- 3. Give only the trial food: (no treats, no table scraps, no flavored medications) exclusively for 8 to 12 weeks, making sure you follow any feeding instructions on the label.
- 4. Keep a food and activity diary: make a note of everything you see including stool condition, scratching, ears, energy, appetite, and if you’re up for it a simple itch score from 0-10.
- 5. STOP: If your dog gets any of the following call your vet immediately.
- Hives or severe itchy skin
- Diarrhea or vomiting
- Swelling of the face
- Anaphylaxis – a rare, life-threatening side effect of the dogs who get antihistamines.
The Bottom Line
Absolutely. Except in the few dogs with a real shrimp, crab or severe mite allergy, black soldier fly larvae protein is a safe, low-risk, probiotic alternative to poultry and beef for most dogs with severe allergies to common proteins. It’s very well tolerated.
It does not generally have cross-reactions with chicken, beef, or dairy. And surprisingly it can even improve skin health! It’s much more sustainable than many traditional meats, too.
The one caveat and it’s an important one is if your dog has a tropomyosin allergy to shrimp, crab, or severe mites. Because that risk is real and significant, you need to consult your veterinarian, no matter what, if your dog’s been itchy and miserable for months. But for everyone else, it can be a game-changing discovery.
Frequently Asked Questions
Can black soldier fly larvae protein cure my dog’s allergies?
No. There’s no cure for food allergies. But a black soldier fly larvae diet can manage the problem by removing the proteins that trigger your dog’s immune system.
How long until I see improvement?
Most dogs will begin to get relief within 4-8 weeks. It can take as long as 12 weeks to get complete relief. So the 8-12 week trial is crucial.
Is it truly hypoallergenic?
We prefer to label it as “new” or “low-allergenic.” No protein is 100% hypoallergenic to any given dog. But most dogs haven’t been introduced to it, being an insect protein.
What about if my dog’s allergic to shrimp or crab?
We discovered in our research that TSA larvae are known to have tropomyosin, the allergen responsible for allergic reactions to crab and shrimp. Cross-reactivity is currently a topic of discussion.
Ask your veterinarian.
Are black soldier fly larvae food complete and balanced?
Yes if it’s a brand from a reputable company. Just make sure that the bag has an AAFCO or FEDIAF statement of nutritional adequacy.
Will my dog eat it?
Surprisingly it’s good. Studies have shown that when black soldier fly larvae were added at 5-10% to food the food was actually more palatable. Many dogs love the flavor.
What are the long-term risks?
Nothing has been seen to date in up to 50 days of feeding showing any adverse blood values, body weight or organ function. Longer term studies are needed, however.
Can I sprinkle the powder on my current food?
No. An elimination diet depends on the black soldier fly larvae being the only source of protein. Adding it to other foods is not an elimination diet.
Is it more expensive than regular dog food?
Yes, usually, it is more expensive than normal dog foods. It’s closer to other specialty diets for allergy, however. As it is becoming more common, the price will be less.
Where can I purchase black soldier fly larvae dog food?
Several companies sell this new diet: Bellfor Tuggs, Local Bounty, Field & Forest, Currant Creek. Always buy from a reputable company and look for a nutritional adequacy statement.
