Maintenance Nutrition for Healthy Adult Dogs
Maintenance nutrition focuses on meeting individual adult dogs’ unique nutritional needs for optimal health and longevity. In addition to individual dogs’ metabolism, nutrition should be tailored by life stage, physical activity, neuter status and breed size, when appropriate.
LIFE STAGE NUTRITION
Labrador Retrievers kept in lean body condition from puppyhood throughout their lives lived nearly 2 years longer than their heavier siblings.
Key Messages
- Nutrition is key to helping dogs live longer, healthier lives.
- Purina studies showed that Labrador Retrievers kept in lean body condition from puppyhood throughout their lives lived nearly 2 years longer than their heavier siblings.
- Keeping dogs lean throughout their lives also may delay onset or decrease severity of age-related diseases such as osteoarthritis.
- Risk of obesity increases for middle-aged dogs, so maintaining a healthy weight and body condition should be a priority throughout adulthood.
- Adult dogs need a nutritionally complete and balanced diet for optimal health and longevity.
- Small (<10 kg [<22 lbs.] at maturity) dogs can benefit from smaller, easy-to-chew kibbles and a slightly more concentrated nutrition to address small dogs’ higher metabolism, smaller stomachs and little mouths.
- Large (25-45 kg [55-99 lbs.] at maturity) and giant (45+ kg [100+ lbs.] at maturity) dogs can benefit from a less calorically dense formula to address large dogs’ slower metabolism and larger stomachs. Large-breed dog foods often include nutrients to support healthy joints and mobility.
- Portion-controlled meal feeding can help keep dogs in optimal body condition.
- The feeding guidelines on the dog food package are a starting point that should be used in conjunction with monitoring body condition.
- Proper portion control, which includes weighing (measuring) the food, helps ensure dogs who may be prone to weight gain are not overfed.
- Meal feeding also allows careful monitoring of food intake and appetite that, if reduced or absent, could signal an underlying health problem.
LIFE STAGE NUTRITION
"Your dog [or dog’s name] is in ideal body condition and that is what is best for [him/her]. Using the feeding guidelines as a starting point for portion sizes, weighing (measuring) the food for each meal, and regularly checking your dog’s body condition can help ensure your dog is getting the nutrition [he/she] needs without being overfed. Just keep in mind that you may need to adjust the food amount if your dog is becoming too heavy or too thin."
