Frequently Asked Questions

What are the essential macronutrients for dogs?

Dogs require a balance of proteins, fats, and carbohydrates. Protein provides essential amino acids for muscle and tissue repair. Fats supply dense energy and support cell structure and nutrient absorption. While carbohydrates are not strictly essential, they provide an accessible energy source and valuable fiber for digestive health.

How do I know if my dog's diet has a nutritional deficit?

Common signs of a dietary deficit include a dull coat, dry or flaky skin, lethargy, unexpected weight loss or gain, frequent gastrointestinal issues, and poor muscle tone. Our deficit calculator can help you estimate invisible gaps in essential nutrients like calcium and protein based on your chosen food.

Why does my dog's breed and size matter for nutrition?

Different breeds and sizes have unique metabolic rates. Large and giant breeds require carefully controlled calcium and phosphorus levels during growth to prevent joint issues. Small breeds often need calorie-dense food because they have higher metabolic rates but smaller stomach capacities.

How much calcium does my dog really need?

Adult dogs generally need around 1.25g of calcium per 1000 calories consumed. Puppies, pregnant, and nursing dogs have significantly higher calcium requirements to support bone growth and milk production. It's crucial not to supplement calcium arbitrarily, as an excess can be just as harmful as a deficiency.

Is it safe to mix kibble with home-cooked or raw food?

Mixing different food types is common, but it can unbalance a complete commercial diet if the additions exceed 10% of your dog's daily caloric intake. If you're adding fresh foods systematically, you must calculate the new macronutrient and micronutrient totals to ensure no deficits are created.

What is the Resting Energy Requirement (RER)?

RER refers to the basic number of calories a dog needs to sustain essential bodily functions while at rest. By applying an activity multiplier to the RER, we determine the Maintenance Energy Requirement (MER), which is the number of calories needed for a dog's daily lifestyle.

What is the canine gut microbiome?

It is a dynamic, co-regulatory partner in your dog's biology that supports digestion, immune regulation, energy metabolism, and temperament.

What causes gut dysbiosis in dogs?

A disruption in the microbiome is primarily driven by age, ultra-processed diets with low fiber diversity, antibiotic use, and chronic stress.

Can I give my dog human supplements to fix these gaps?

No. While some ingredients overlap, human supplements often contain ingredients that are highly toxic to dogs, such as Xylitol, Alpha-Lipoic Acid, and Resveratrol.

What are the best probiotics for dogs?

Multi-strain synbiotics are best, particularly heat-stable spore-forming probiotics (like Bacillus subtilis) paired with diverse prebiotics and postbiotics.

What is the difference between BCS and MCS?

Body Condition Score (BCS) measures body fat on a 9-point scale. Muscle Condition Score (MCS) specifically evaluates muscle wasting over areas like the temporal bones, scapulae, and lumbar vertebrae. A dog can be overweight (high BCS) but still suffer from severe muscle wasting (low MCS) due to a low-protein diet.

How do you restore gut balance after antibiotic use?

Clinical recovery often involves the use of synbiotics (the combination of prebiotics and probiotics). Utilizing a high-quality synbiotic introduces beneficial bacteria while simultaneously providing the specific dietary fibers required to nourish and establish those strains in the sterile gut.
