Homemade food vs. supplements: are you risking hidden nutrient deficiencies?
Lucia Hrivnakova
Introduction and purpose of the article
For many dog parents , cooking for their four-legged friend is a show of love and a way to avoid preservatives and low-quality ingredients in industrial food. Trends for 2025 show that natural foods, supplements and human-grade ingredients are among the fastest-growing segments of the pet food industry. At the same time, demand for probiotics and functional supplements is growing, with searches for “dog probiotics” increasing by 91% in five years. This leaves dog owners wondering: Is homemade food enough, or am I risking hidden nutrient deficiencies? This article offers an in-depth look at the benefits and risks of homemade food, explains which nutrients are often missing, why veterinarians recommend supplements and how it all connects to Havvi products.
A story from life: when good intentions are not enough
"Lucia started cooking chicken thighs with rice and carrots for her Labrador. After a few weeks, she noticed that the dog's coat was losing its shine and seemed tired. The vet found a calcium and vitamin deficiency because she wasn't feeding her homemade diet with any supplements. After adding a multivitamin and probiotics, both his energy and coat quality returned."
This experience is not unique. Homemade foods may be high quality , but if they are not nutritionally balanced, your dog may be lacking key nutrients.
Why cook at home at all?
-
Control over ingredients: By cooking, you can eliminate allergens, artificial colors, and flavors.
-
Freshness and taste: Homemade foods tend to be more appealing to picky dogs and can improve the appearance of their coat and skin.
-
Monitoring special needs: Dogs with specific intolerances or diseases may benefit from a customized diet (e.g. low phosphorus for kidney disease).
Risks and most common nutritional deficiencies
The complexity of a balanced diet
Veterinary sources warn that homemade diets without professional advice can cause both deficiencies and excesses of nutrients . VCA Animal Hospitals emphasizes the need to use recipes from veterinary dietitians and supplement them with vitamin-mineral supplements to avoid trace element deficiencies. A dog needs six basic nutrients (water, carbohydrates, vitamins, minerals, fats and proteins) and their ratio varies according to age, activity and health status. .
Drawbacks of cooking by intuition
Rover.com warns that unbalanced recipes can lead to serious health problems ; many homemade meals require supplements or deficiencies will develop. The most common deficiencies are:
| Nutrient | Why is it important? | Risk of shortage | Natural resources |
|---|---|---|---|
| Calcium | Bone and tooth structure, cardiovascular and nervous systems | When deficient, the body draws calcium from the bones, which leads to their weakening. | Bones (raw), sardines, eggshells; often missing from home-cooked meat dishes |
| Vitamin B12 | Supports blood cell production and the immune system | Deficiency reduces the ability to absorb iron and can cause anemia. | Liver, fish, eggs; may be low in muscle |
| Magnesium | Energy metabolism, cardiac and muscular activity | Deficiency causes weakness, arrhythmias, and behavioral changes | Leafy greens, nuts; servings tend to be low when cooked |
| Choline | Liver, brain and nerve function | Deficiency leads to vomiting, liver problems, and high cholesterol | Meat, eggs; need to be supplemented if dog is not getting organ meats |
| Vitamin D and Omega-3 | They support calcium absorption, immunity and skin health | Deficiency can affect bone and coat health | Fatty fish (salmon, sardines); many home recipes do not include them |
Other risks
-
Bacterial contamination and raw meat: The American Veterinary Medical Association and the FDA do not recommend BARF/raw diets due to the risk of salmonella and pathogens. Cooking reduces the risk, but hygiene and proper storage are important. .
-
Bones and cooked bones: Boiled bones can splinter and cause internal injuries.
-
Improper dosage: An inappropriate ratio of proteins, fats, and carbohydrates can lead to obesity, diabetes, joint problems, or digestive problems.
-
Life stage: The needs of puppies, pregnant bitches, seniors, or active dogs vary; without adaptation, deficits can arise .
Why use supplements and how to choose quality ones
-
Supplementing missing nutrients: Most homemade recipes require a complex vitamin-mineral mix (so-called premix) .
-
Veterinary supervision: Each dog is individual and needs a different ratio of nutrients; a veterinary dietitian should recommend appropriate supplements and check blood values
-
Quality and Safety: The American Association of Supplements (NASC) only awards its seal of quality to manufacturers with strict controls Avoid supplements with unverified marketing claims.
-
Havvi Products: Our supplements ( Longevity Complex , Mobility Elixir, Calm & Relax and Digestive Harmony ) are based on pure ingredients, contain a premix of minerals and vitamins and are developed by veterinarians. They help replenish calcium, vitamins B, D and omega-3, probiotics and herbs for better digestion, joints, longevity and mental health of the dog.
Veterinary tips
-
Consultation before changing diet: If you plan to switch to home cooking, consult a veterinarian or certified dietitian; in case of illnesses or special needs, a professional is essential .
-
Follow approved recipes: Use proven recipes with all listed supplements – omitting the premix can lead to “numerous nutritional deficiencies” .
-
Limit raw meat and cooked bones: The risk of infections and damage to the digestive tract is higher.
-
Monitor weight and coat condition: Too much fat or carbohydrates can lead to weight gain; a dull coat or fatigue are often the first signs of nutrient deficiencies.
