Royal Canin Chihuahua Review: Honest Take + 5 Alternatives

This post contains affiliate links.

If you have a Chihuahua at home and you’ve walked into a vet’s office, someone probably offered you Royal Canin Chihuahua as “the breed-specific option.” It’s one of the best-known brands, one of the most recommended, and also one of the most expensive on the market. The inevitable question: is it really worth paying more for a breed-specific food? Is it better than other equally prestigious options? And if your Chihuahua won’t eat it, are there alternatives just as good?

In this Royal Canin Chihuahua review we cover what makes the food distinctive (in its puppy and adult versions), the pros and cons from the perspective of a real owner rather than a brand, and which alternatives are worth considering. No marketing, no paid recommendations, no allegiance to any company. Just what we saw, read, and discussed with vets who know the breed.

This article is informational and does not replace veterinary advice, especially if your Chihuahua has digestive issues, allergies, weight problems, or any specific condition. Every dog is unique.

What makes Royal Canin Chihuahua special?

Royal Canin is a French brand with decades of research in canine nutrition. The Chihuahua line (also sold as Chihuahua Adult and Chihuahua Puppy) is designed specifically for the breed, with three real particularities:

1. Kibble shape and size: very small, with a shape that fits the Chihuahua’s small jaw. This helps the dog chew it instead of swallowing it whole, a common habit in toy dogs.
2. Composition adapted to energy needs: Chihuahuas have a fast metabolism and need nutrient-dense food so they don’t have to eat large volumes.
3. Specific additives: it includes fatty acids to support the coat (Chihuahuas can have a shiny or dull coat depending on diet) and compounds that help control bad breath, a frequent problem in the breed.

Is the science exclusive? No. Other premium brands also research small breeds and produce adapted kibble. But Royal Canin was among the first to position a food “for Chihuahuas,” and that gave it a prestige it still holds.

What are the pros of Royal Canin Chihuahua?

The good, without sugarcoating:

• Kibble well thought out for jaw size: in practice, Chihuahuas eat it without choking and usually like it.
• Wide availability: you’ll find it in almost any vet clinic, pet store, large supermarket, and online.
• Recommended by many vets: it has professional backing, which is reassuring if you don’t have much experience.
• Stable formula: the recipe doesn’t change often, so your dog doesn’t have to keep adapting.
• Good palatability: most Chihuahuas accept it without trouble, even picky ones.
• Good nutrient density: a small amount covers daily needs, which helps a breed prone to weight gain.

What are the cons of Royal Canin Chihuahua?

Not everything is positive, and it’s important to say so:

• High price: one of the most expensive brands on the market. The gap with other premium options is significant.
• Composition isn’t the best in the premium segment: it contains a notable proportion of grains (corn, rice) as a carbohydrate source. Newer brands like Acana or Orijen have much more meat and less grain in proportion, though they’re also pricier.
• Not hypoallergenic: if your Chihuahua is allergic to common proteins (chicken, beef), this isn’t the best option. There are specific hypoallergenic lines for that.
• Some Chihuahuas refuse it: palatability is good but not universal. Some dogs reject the flavor.
• Can cause digestive upset in sensitive dogs, especially when switching foods without a gradual transition.

Are there alternatives just as good or better?

Yes, several. The right choice depends on your budget, what your Chihuahua will accept, and your vet’s specific recommendations. Here are the most relevant:

Acana Adult Small Breed

Superior nutritional quality in terms of meat percentage (60–65% vs. roughly 25–30% in Royal Canin). Grain-free or low-grain. More expensive than Royal Canin, but many vets prefer it for Chihuahuas with digestive sensitivities.

Orijen Original or Six Fish

From the same company as Acana, but higher in animal protein (around 85%). Excellent for active dogs or those with a dull coat. The priciest option on the list.

Eukanuba Small Breed Adult

Similar in composition to Royal Canin but generally more affordable. A good alternative if you want standard quality without paying the brand premium.

Hill’s Science Diet Small & Mini Adult

Another vet-recommended brand. Solid composition, price close to Royal Canin. Good if your dog has dental issues or needs weight control.

Purina Pro Plan Small Breed Adult

More accessible than Royal Canin, with decent composition. Not premium-superior, but it does the job for Chihuahuas with no special needs.

Brand	Meat in composition	Relative price	Recommended for
Royal Canin Chihuahua	Medium	High	Standard Chihuahua, no sensitivities
Acana Small Breed	High	High	Chihuahua with digestive sensitivity
Orijen Original	Very high	Very high	Active dogs, shiny coat
Eukanuba Small Breed	Medium	Medium	More affordable alternative
Hill’s Science Diet	Medium	High	Dental issues, weight control
Pro Plan Small Breed	Medium-low	Medium	Tight budget, healthy Chihuahua

Where to buy Royal Canin Chihuahua

When is Royal Canin Chihuahua worth it?

After reviewing everything, my honest opinion: it’s worth it in these specific cases:

• Chihuahua with no allergies or sensitivities: if your dog eats everything and is healthy, Royal Canin is a reasonable choice.
• Owners who aren’t nutrition experts: the brand does the work of designing the formula. If you don’t want to analyze labels, it’s a safe option.
• A picky dog that already likes it: if your Chihuahua accepts Royal Canin and you don’t want to experiment, there’s no reason to change.
• Recently weaned puppies: the Royal Canin Chihuahua Puppy version is well formulated for the first months. For more on that stage, see Chihuahua puppy care.

It’s not worth paying for if:

• Your Chihuahua has allergies or digestive sensitivities (better to go hypoallergenic or truly premium).
• You want the best possible nutritional quality (Acana or Orijen win on meat and composition).
• Your budget is tight and you want a solid, cheaper food (Eukanuba or Pro Plan deliver).
• Your vet recommends something specific for a health condition.

What about a raw or homemade diet?

It’s a valid option but requires much more responsibility. A poorly planned raw or homemade diet can cause serious nutritional deficiencies, especially in a small breed like the Chihuahua. If you go that route, work with a veterinary nutritionist who builds the plan around your dog’s weight, age, and condition. Don’t improvise with internet recipes.

For most owners, a well-chosen premium kibble is safer, cheaper, and nutritionally more balanced than a homemade diet without guidance.

The bottom line

• Royal Canin Chihuahua is a good option, but not the only good one.
• Its biggest advantages are the kibble shape and wide availability.
• Its biggest drawback is the high price and a composition with quite a bit of grain.
• Alternatives like Acana, Orijen, Eukanuba, or Hill’s can be equal or better depending on the case.
• Most important: the food your Chihuahua accepts and digests well.
• Always check with your vet before switching brands.

I fed Romeo Royal Canin for years and it suited him well: shiny coat, steady energy, calm digestion. I switched him to Acana a while back because of a mild chronic itch I suspected was grain-related, and the improvement was clear. Lorenzo, on the other hand, eats Eukanuba Small Breed: same family budget, no problems, he likes it and holds his weight. Which is the best brand? The one your Chihuahua eats well, digests well, and you can sustain over time. Don’t be swayed by the “breed-specific” label alone: read the composition, watch how it sits with your dog, and check with your vet. Your Chihuahua deserves a decision based on him, not on the packaging.
