Puppy Nutrient Needs

A puppy’s stage is arguably the most important because it sets the foundations for life.

Your Miniature Schnauzer eventually grows into an 11 to 20-pound adult, and his first year is all about providing the best food to help him develop healthily. It pays dividends for his long-term health to feed him high-quality food. He is weaned off his mother’s milk at around six weeks old, so by the time you bring him home, he’ll be ready for dog food.

The most important thing you can do is to feed food designed for puppies. Puppy food contains more protein and fats for healthy development. In particular, docosahexaenoic acid (DHA) and arachidonic acid (ARA) are important fats for puppy growth. They support healthy cognitive and vision development, as well as overall wellness. Ingredients that supply these healthy omega fats are meat meals, fish, fish oils, and eggs.

Formulas designed for small breeds contain more energy per pound than all-breed or large-breed dog foods. Plus, the kibble pieces are small enough for your little pup to eat them comfortably. High-quality food also contains a variety of vitamins and minerals. These are essential during puppyhood because they support the development of a strong immune system. Look for fruits, veggies, and added supplements.

As we said, the protein content is higher in puppy food. The Association of American Feed Control Officials (AAFCO) recommends that all puppies need a minimum protein content of 22%. Protein is essential for growth and muscle care because it is full of amino acids, which all living things need. Meat protein should always be the first ingredient.

Adult Nutrient Needs

If your Schnauzer is more gassy than normal, it could be his food.

At around 12 months, you should switch your Miniature Schnauzer to adult food. He has completed most of his growing now, so energy-rich puppy kibble is no longer needed. Adult foods focus on a more balanced diet to maintain a healthy body. Again, stick to small-breed dog foods that are small enough for your Schnauzer to eat with ease.

AAFCO recommends that adult dogs should eat a protein content of at least 18%. In addition to real meats, meat meals are a great source of protein. They are also a great source of healthy omega fats and glucosamine needed for joint support. Some dogs are intolerant of certain meats, and it’ll give them bad gas. Be sure to try new flavors, or a limited ingredient food, if your Schnauzer is gassy.

Prebiotic fiber helps with regular digestion and keeps dogs feeling fuller in between mealtimes. Peas, chicory root, beet pulp, and pumpkin are great sources of fiber to look for. Probiotic ingredients such as dried lactobacillus plantarum fermentation product promote friendly bacteria in his gut. These also lead to better digestion and less gas. Also, look for antioxidant-rich ingredients, such as blueberries and cranberries, for continued strong immunity.

Senior Nutrient Needs

Your dog’s bones and joints experience more stressed with age.

When your Miniature Schnauzer reaches approximately eight years of age, it’s time to switch him to senior food. Once again, his nutritional needs are beginning to change. It’s different for every dog, but when he starts to put on weight and slow down activity, it’s time. Slowly transition him to avoid stomach upset.

Older dogs need much less energy than they did during adulthood, even sassy Schnauzers. Senior dog foods are lower in fats, calories, and often protein. Many senior options have a higher fiber content as fiber is low in calories. Plus, it bulks out his dinner, meaning he’ll feel fuller for longer. It’s important to keep your pooch trim. Otherwise, he’s more likely to suffer from weight-related health conditions.

High-quality senior formulas contain higher amounts of glucosamine and chondroitin, as these support joint health. Look for ingredients such as meat meals, fish, fish oil, cartilage, green-lipped mussels, and added glucosamine supplements. And to keep his immunity fighting fit, look for extra vitamins and minerals.
