Do you know how much your dog should eat?<\/h2>\n\n\n\n

Nutrition is one of the most important factors influencing the health and well-being of dogs. Nowadays, knowledge about proper nutrition and the importance of diet for animal well-being allows both veterinarians and owners to keep their pets in optimal condition throughout their lives.
For dogs, as for all mammals, food is a source of nutrients that ensure proper growth, development, and a healthy life. So, is there a single, universal feeding method?
A complete and balanced diet is one that contains all essential nutrients in the right amounts and proportions. The food must be digestible and absorbable to provide the animal with the necessary energy. However, there is no one-size-fits-all feeding method, as every dog is different \u2013 breed, age, activity level, and health are just some of the factors that influence daily energy requirements. That's why it's so important to know, how much should a dog eat<\/strong> \u2013 in relation to his individual needs.<\/p>\n\n\n\n

What influences a dog's daily calorie requirement?<\/strong><\/h2>\n\n\n\n

A dog's body needs energy to survive, grow, function, and regenerate. The energy provided through food (protein, fat, carbohydrates) must be tailored to the animal's physiology and lifestyle. To find out, how much should a dog eat<\/strong> several key factors need to be analyzed:<\/p>\n\n\n\n

Weight and size of the dog (breed)<\/strong><\/h3>\n\n\n\n

Body weight and breed are the basis for determining daily calorie intake. The larger the dog, the more energy it requires\u2014but not in direct proportion to weight. Miniature dogs have higher calorie requirements per kilogram of body weight than giant dogs.<\/p>\n\n\n\n

Dog's age (puppies, adults, seniors)<\/strong><\/h3>\n\n\n\n

Puppies need more energy per kg of body weight than adult dogs as they grow, learn, and develop. Senior dogs, on the other hand, may need fewer calories if they are less active. It's always worth checking, how much should a dog eat<\/strong> at a given age and adjust the portion.<\/p>\n\n\n\n

Castration\/sterilization<\/strong><\/h3>\n\n\n\n

After neutering, the levels of hormones responsible for metabolism decrease. Neutered dogs tend to be overweight \u2013 their daily energy requirements decrease. This is when it's important to monitor, how much should a dog eat<\/strong>, so that he doesn't gain weight.<\/p>\n\n\n\n

Your dog's physical activity level<\/h3>\n\n\n\n

A couch potato needs fewer calories than a herding dog, a tracking dog, or an athlete. The more exercise, the greater the energy burn and the higher the caloric needs. Feeding should be adjusted to the dog's activity level and monitored regularly.<\/p>\n\n\n\n

The dog's health condition<\/strong><\/h3>\n\n\n\n

Dogs suffering from chronic illnesses, digestive disorders, or those undergoing convalescence require special nutritional support. Diet therapy is an integral part of treatment, and nutritional prevention helps prevent relapses. It's worth seeking the help of a canine dietitian who will assess, how much should a dog eat<\/strong> in a given clinical condition.<\/p>\n\n\n\n

How to calculate a dog's daily calorie intake?<\/h3>\n\n\n\n

Arrangement, how much should a dog eat<\/strong> requires a thorough analysis of your body weight, fitness level, and lifestyle. Daily calorie requirements are based on the so-called. metabolic energy<\/strong>, that a dog's body uses to function. Calculating your dog's calorie needs is the first step to properly balancing its diet.<\/p>\n\n\n\n

Ideal body weight assessment<\/strong><\/h3>\n\n\n\n

The calculations should start by determining ideal body weight of a dog<\/strong>. For purebred dogs, you can use the breed standard. For mixed-breed dogs, we use a 9-point scale. Body Condition Score (BCS)<\/strong>, which determines the dog's condition from extreme emaciation to obesity. This helps to better determine, how much should a dog eat<\/strong>, to achieve or maintain an ideal figure.<\/p>\n\n\n

Metabolic Energy and Modified Atwater Coefficients<\/h3>\n\n\n\n

The energy used by the body is defined as metabolic energy (ME)<\/strong>. It is calculated based on the nutrient content of the food\u2014protein, fat, and carbohydrates\u2014according to the modified Atwater coefficients. This energy should be the basis for calculating daily calorie intake.<\/p>\n\n\n\n

Basic Energy Requirement (RER)<\/h3>\n\n\n\n

The first step is to calculate RER (Resting Energy Requirement<\/em>)<\/strong> \u2013 resting energy requirement of a dog:<\/p>\n\n\n\n

RER = 70 \u00d7 (body weight in kg)0,75<\/sup><\/strong><\/sup><\/p>\n\n\n\n

This formula allows you to determine how many calories a dog needs at rest, without taking into account physical activity, age, or health status. It's a starting point for further calculations that will answer the question, how much should a dog eat<\/strong> in practice.<\/p>\n\n\n\n

Daily energy requirement (DER\/MER)<\/h3>\n\n\n\n

The next step is to calculate DER (Daily Energy Requirement<\/em>)<\/strong> - or MAYOR<\/strong> (Maintenance Energy Requirement<\/em><\/strong>) \u2013 i.e., the actual energy requirement. To do this, we multiply the previously obtained RER by a factor corresponding to the dog's lifestyle:<\/p>\n\n\n\n

Type of dog<\/strong><\/td>DER (x RER)<\/strong><\/td><\/tr><\/thead>
Adult neutered dog<\/td>1,6<\/td><\/tr>
Adult dog, not neutered<\/td>1,8<\/td><\/tr>
Obese dog, inactive<\/td>1,4<\/td><\/tr>
Weight loss dog<\/td>1,0<\/td><\/tr>

A dog is recovering<\/td>1.2\u20131.4<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Thanks to this, we are able to accurately estimate, how much should a dog eat<\/strong>, to meet your daily energy needs.<\/p>\n\n\n\n

How to convert calories into food portions?<\/strong><\/h2>\n\n\n\n

To convert the calculated calories into a specific portion of food<\/strong>, we need to know energy density of food<\/strong>, i.e. the number of kcal\/100 g. This information can be found on the product label. For example:<\/p>\n\n\n\n
