In-depth reviews
Royal Canin Veterinary Diet Hydrolyzed Protein Adult HP Dry Dog Food review
This prescription diet is often a first choice for vets who suspect a true food allergy. The protein is hydrolyzed, which means it is broken into very small pieces that the immune system is less likely to recognize as an allergen. That makes it ideal for strict elimination diets where you need to see if food is driving your Frenchie’s itching, ear infections, or chronic gut issues.
The kibble is highly digestible and moderately low in fat, which can also help French Bulldogs that struggle with loose stools or pancreatitis risk. It is not the most exciting food flavor-wise, but for many dogs the tradeoff in symptom relief is worth it. Compared with something like Hill’s Science Diet Sensitive Stomach & Skin, this formula is more specialized and usually works better for clear allergy cases, but it costs more and requires a veterinary prescription.
The main drawbacks are price and access. You will need your vet to approve and write a prescription, and it can be more expensive than regular premium kibble. This is usually not a forever food for mild sensitivities, but a powerful diagnostic and management tool for serious cases.
Hill’s Science Diet Sensitive Stomach & Skin Small & Mini Adult review
Hill’s Science Diet Sensitive Stomach & Skin Small & Mini Adult is a good starting point if your Frenchie has mild to moderate digestive upset or skin issues but does not need a prescription formula. It is built around easily digestible ingredients, prebiotic fiber, and added omega 6 fatty acids and vitamin E to support skin and coat health. The kibble size is tailored for small breeds, which matters for Frenchies with broad heads and short muzzles.
For many dogs, simply moving to a gentle, highly digestible food like this cuts back on gas, soft stools, and some itch. Compared with the Royal Canin hydrolyzed diet, Hill’s is easier to buy, more affordable, and more palatable for many dogs, but it is not truly hypoallergenic. If your dog has a confirmed allergy to chicken or eggs, you will want to look instead at a limited ingredient formula such as Blue Buffalo Basics.
The biggest downside is that it still uses common proteins and grains, so it will not solve symptoms for every allergic dog. It is best for Frenchies whose issues may be from general sensitivity or mild intolerance rather than a full immune allergy.
Blue Buffalo Basics Skin & Stomach Care Grain Free Turkey & Potato Recipe review
Blue Buffalo Basics Grain Free Turkey & Potato is a limited ingredient diet made to simplify what hits your Frenchie’s system. It features turkey as the single animal protein, with potatoes and peas as the main carbohydrate sources and no chicken, beef, dairy, or eggs. That makes it a useful choice if you suspect your dog reacts to the most common proteins.
The formula includes pumpkin and prebiotic fiber to support digestion, as well as omega 3 and 6 fatty acids from fish oil and flaxseed for skin and coat. Compared with Hill’s Sensitive Stomach & Skin, this food is more targeted toward potential allergies and is completely grain free, which some owners prefer. Against a prescription option like Royal Canin Hydrolyzed, it is less strictly controlled but more affordable and easier to transition to for long term feeding once you have identified safe ingredients.
Potential drawbacks include that grain free is not necessary or ideal for every dog, and peas and potatoes are not appropriate for all Frenchies, especially those with specific cardiac or metabolic issues. It is wise to discuss grain free and pulse-heavy diets with your vet before committing, especially for long term use.
The Farmer’s Dog Turkey Recipe Fresh Dog Food review
The Farmer’s Dog Turkey Recipe is a fresh, lightly cooked food that arrives frozen in pre-portioned packs. The ingredient list is short and recognizable, typically including turkey, chickpeas or quinoa, vegetables, and added vitamins and minerals. For some French Bulldogs with sensitive stomachs or who refuse dry kibble, the softer texture and aroma of fresh food can be a game changer.
This recipe can work well for Frenchies who have mild food sensitivities, occasional loose stools, or dull coats rather than severe, vet-confirmed allergies. It tends to be easier to digest than many dry foods and can help some dogs maintain lean muscle while avoiding fillers. Compared with Blue Buffalo Basics or Hill’s Sensitive Stomach & Skin, The Farmer’s Dog is more expensive per meal and requires freezer space and more planning, but offers human-grade ingredients and a more customizable feeding experience.
The main downsides are cost and convenience, especially for larger or multi-dog households. It is also not a true hypoallergenic prescription food, so if your Frenchie has complex allergy issues, you may still need to use something like Royal Canin Hydrolyzed under your vet’s guidance first, then transition to a fresh formula that avoids known triggers.
Common allergy triggers in French Bulldogs
French Bulldogs are prone to both environmental and food allergies, and it can be hard to tell which is which. Common food triggers include chicken, beef, dairy, egg, wheat, and sometimes soy. Some dogs also react to certain fish proteins or to multiple ingredients at once.
Typical signs that food might be involved include year-round itching, recurring ear infections, face rubbing, licking or chewing paws, redness in armpits or groin, and chronic soft stool or gas. Environmental allergies often flare seasonally, while food allergies tend to be more constant, but many Frenchies have a mix of both. Keeping a log of flare-ups, diet changes, treats, and new foods can help you and your veterinarian connect the dots.
Because symptoms overlap with other conditions such as mites, yeast, or bacterial skin infections, a vet exam is essential before blaming food alone. Your vet may recommend a strict elimination diet using a prescription hydrolyzed formula or a carefully designed novel protein diet to confirm food allergies.
How to switch your French Bulldog to a new food safely
Once you choose a new food for your allergic Frenchie, how you transition matters just as much as what you buy. A slow, deliberate change reduces the risk of diarrhea, vomiting, or gas that can confuse the picture when you are trying to judge whether the new food helps. For most dogs, a 7 to 14 day transition works well.
Start with about 25 percent new food mixed with 75 percent old food for 2 to 3 days. If your dog is doing well, move to a 50/50 mix for another few days, then 75 percent new and 25 percent old, and finally 100 percent new food. If you are doing a strict elimination trial with a prescription diet like Royal Canin Hydrolyzed, your vet may ask you to move faster or slower depending on your dog’s history.
During this time, cut out all other variables as much as possible. That means no flavored medications, table scraps, or random treats unless they are approved as safe by your vet. It usually takes at least 6 to 8 weeks on a tightly controlled diet to see full improvement in skin and ear symptoms, so try to be patient and consistent.
Final thoughts
Finding the best dog food for a French Bulldog with allergies is part science and part patience. If your dog has severe, long-running issues, start with a veterinary visit and consider a prescription option like Royal Canin Hydrolyzed Protein to get clear answers. For milder sensitivities, gentle everyday foods such as Hill’s Sensitive Stomach & Skin, a limited ingredient diet like Blue Buffalo Basics, or a fresh option like The Farmer’s Dog can each be smart starting points.
Whichever food you choose, introduce it slowly, track symptoms, and stay in close communication with your veterinarian. With steady testing and careful feeding, most Frenchies can find a diet that lets their skin calm down, their digestion settle, and their personality shine again.

FAQ
How do I know if my French Bulldog’s allergies are from food or something else?
Food allergies usually cause year-round symptoms such as itching, recurring ear infections, face rubbing, and paw chewing, often along with gas or soft stools. Environmental allergies from pollen, dust, or mites can look similar but often flare seasonally or in certain locations. The only reliable way to confirm food allergies is through a structured elimination diet guided by your veterinarian, along with ruling out other issues such as infections or parasites.
What protein is best for French Bulldogs with allergies?
The best protein is usually one that your dog has rarely or never eaten before, such as turkey, duck, venison, or certain types of fish. For more severe cases, hydrolyzed protein diets break the protein into pieces that the immune system is less likely to react to. Work with your vet to review your Frenchie’s full diet history so you can pick either a truly novel protein or a hydrolyzed prescription food for the most accurate trial.
Is grain free food better for French Bulldogs with allergies?
Not automatically. Most food allergies in dogs are to proteins like chicken or beef, not to grains. Some Frenchies do feel better on grain free diets, especially if they are also limited ingredient, but grain free formulas that rely heavily on peas, lentils, or potatoes may not be ideal for every dog. Discuss pros and cons with your veterinarian before switching, especially if your Frenchie has heart or metabolic concerns.
How long does it take for a new food to help my Frenchie’s allergies?
Digestive symptoms such as gas or soft stools can improve within a few days to a couple of weeks after a careful transition. Skin, ear, and paw issues take longer, often 6 to 8 weeks or more, because inflammation and infections need time to clear. During that period, it is crucial to feed only the approved diet and treats so you can truly judge whether the food is working.
Can I make homemade food for my French Bulldog with allergies?
Homemade food can help in some cases because you control every ingredient, but it is easy to create nutrient imbalances, especially for a small, stocky breed like the French Bulldog. If you want to go this route, talk with your vet about involving a board-certified veterinary nutritionist who can design a balanced recipe that avoids your dog’s triggers. In many cases, a well-formulated commercial limited ingredient or hydrolyzed diet is a safer starting point.
