Diamond Naturals Senior Formula is an average-quality dry dog food. Its nutrient profile is above average and as a consequence, it has above-average quantities of protein and fat. It’s carbohydrate proportion, however, is excessive and should be notably lower to better reflect a dogs natural diet. The formula contains a small range of high-quality ingredients with a focus on poultry such as Chicken and Chicken Meal. A range of grains are present and they provide a source of carbohydrates. In addition to this, they provide fiber for healthy digestion. Brown Rice and Oatmeal are two of the better grains seen in dog food and should not be a significant concern. Diamond Naturals Senior Formula range of ingredients may make it unsuitable for those with dietary sensitivities and allergies. Nevertheless, this is one of the most nutritious and high-quality senior dog foods on the market.

Excessive Carbohydrate Proportion Contains Rice Bran
A Full review of Naturals Senior Formula By Diamond
The ideal nutrition for a dog is entirely dependant on their unique circumstances. However, a high proportion of protein and fat combined with a lower proportion of carbohydrates is most appropriate nutrition profile for the vast majority of dogs. Dog’s are very capable of consuming a high proportion of carbohydrates, but a diet high in protein and fat is more appropriate and a better reflection of their natural ancestral diet.
Carbohydrate Content Analysis
Dogs use carbohydrates as a simple energy source. Dogs do not require significant carbohydrates in their diet and they are commonly added to reduce cost and increase shelf life. As the chart above displays, a maximum of 48% of Diamond Naturals Senior Formula calories are derived from carbohydrates. Please note that this is the maximum amount of carbohydrates as calculated by the guaranteed analysis. In reality, this value of carbohydrates is likely to be a lot lower. This is average for a Senior Dog Food.
Peas, Brown Rice, and Oatmeal among others are the core of the carbohydrate content of Diamond Naturals Senior Formula. While there may be a number of sources, none of these are considered low-quality carbohydrate sources. This is a very significant proportion of carbohydrates for a senior dog and we believe it should be notably lower to better reflect a dogs natural diet.
Protein Content Analysis
Dogs use Protein for growth, development, and maintenance. Excess protein can be burned as calories. As the chart above displays, a minimum of 26% of Diamond Naturals Senior Formula calories are derived from protein. Please note that this is the minimum amount of protein as calculated by the guaranteed analysis. In reality, this value of protein is likely to be higher. This is above average for a Senior Dog Food.
While not quite as high as some Diamond dry dog food recipes, this level of protein is satisfactory for the average senior dog. Contrary to popular belief, senior dogs do not need a reduced protein diet and they may, in fact, need additional protein than younger dogs. Therefore a satisfactory proportion, such as this, is critical. The protein content is sourced from a mix of poultry and Eggs. The Chicken, Chicken Meal, and Eggs are high-quality protein sources.
Fat Content Analysis
Dogs use fat as a concentrated energy source. In addition, fats also play a role in development and maintenance. As the chart above displays, a minimum of 26% of Diamond Naturals Senior Formula calories are derived from Fat. Please note that this is the minimum amount of fat as calculated by the guaranteed analysis. In reality, this value of fat is likely to be a lot higher. This is average for a Senior Dog Food.
It will come as no surprise that animal fats constitute the majority of Diamond Naturals Senior Formula fat content. Animals fats such as Chicken fat are the ideal energy source for senior dogs. Sadly, the level of the Omega 3 Fatty Acids in this formula is quite low and is unlikely to provide a noticeably benefit.
Overall Diamond Naturals Senior Formula contains an average of 3,400 kcal/kg or 318 kcal/cup
Once again please note that the values in this section are calculated using the products guaranteed analysis. The guaranteed analysis only lists the minimum and maximum values and as a consequence, these can sometimes be an inaccurate representation. As a rule of thumb, most dog foods will contain slightly more protein and considerably more fat than their guaranteed analysis. This will have the knock-on effect of reducing the relative amount of carbohydrates present. However also note that every dog food is different and some will be considerably closer to the guaranteed analysis than others.
Guaranteed Analysis – Diamond Naturals Senior Formula
Pet foods in the United States are legally required by the AAFCO to have a guaranteed analysis on their packaging. A guaranteed analysis must display certain nutritional information. This is similar to how nutritional values are now commonly displayed on food for human consumption. The information that must be displayed includes Crude Protein, Crude Fat, Crude Fiber, and Moisture. Some guaranteed analysis will contain additional information. The guaranteed analysis for this product is listed below.
- Crude Protein (Min) – 25.00%
- Crude Fat (Min) – 11.00%
- Crude Fiber (Max) – 4.00%
- Moisture (Max) – 10.00%
- Omega 6 Fatty Acids (Min) – 2.20%
- Omega 3 Fatty Acids (Min) – 0.30%
The ingredients of pet food are disclosed on the packaging of the product as a list in descending order. Therefore the ingredients at the start of the list make up the bulk of the pet foods content. As a consequence, the quality of these primary ingredients is the most significant factor in determining the quality of pet food.
However, ingredients listed further down the ingredient list should not be ignored, especially if they could have adverse or harmful effects on a pet.
- Chicken Meal
Dangerous / Harmful Ingredients
In-Depth Meat/Fish Ingredient Review
The meat and fish ingredients of dog food are without a doubt the most important. They are critical as they provide the majority of the protein and fat that dogs desperately need. Also, these ingredients would have made up the bulk of dogs ancestors diet. Therefore, the quality of a dog food formulas meat and fish ingredients is crucial. Diamond Naturals Senior Formula contains three sources of meat or fish.
The primary meat source present is Chicken. Chicken is considered a high-quality source of protein. In addition to being a fantastic protein source, chicken has high levels of Niacin and Vitamin B6. Unfortunately Chicken does contain a high concentration of water. Much of this water is evaporated during the cooking process leaving a lesser proportion of Chicken. However given that Chicken is the first listed ingredient, its proportion will still be relatively high even after the cooking process.
The secondary meat source present is Chicken Meal. Chicken Meal is considered a high-quality source of protein. Meat Meal is a concentrated form of meat that has already had the majority of its moisture removed. This means that gram for gram it is much richer in protein and other nutrients. Chicken Meal will contain the same vitamins and minerals as Chicken but in higher concentrations. This includes high levels of Niacin and Vitamin B6.
Eggs are a highly nutritious pet food ingredient and are considered a high-quality source of protein. Eggs contain a huge variety of vitamins and minerals including Vitamin A, Vitamin B2 and B12, Selenium, Phosphorus and many others. In addition to this, they contain a high proportion of protein and healthy fats such as the Omega 3 and 6 Fatty Acids.
In-Depth None-Meat Ingredient Review
Despite being a grain, Brown Rice can provide some nutrition. Therefore it is considered one of the better grains. To add to this Brown Rice is far superior to White Rice which is heavily processed. Brown Rice can provide dietary fiber for healthy digestion and high levels of Magnese.
Diamond Naturals Senior Formula contains Peas. These are members of the legume family of vegetables. Legumes are famous for having a relatively high amount of protein for a vegetable. Legumes also contain a high amount of fiber, which is essential for healthy digestion. Pet foods often use legumes as a replacement for grains in grain-free pet food. Protein from vegetables such as legumes should not be a replacement for protein from meat. Instead, it should act as an additional protein source.
Oatmeal is made from the grinding of Oats. Oats are a grain and in their pure form do not contain gluten. However, oats and oatmeal are considered one of the better grains for a dogs diet. Oats are high in fiber, very high in plant-based proteins and have some vitamins like Vitamin B5 and B9.
Dried Beet Pulp is a by-product of sugar beet processing. It is added to pet food as a source of soluble fiber. This fiber helps absorb excess water in your pets digestive system, as well as promote healthy bowel movement and stool. Dried Beet Pulp does not contain any significant nutritional value.
Dried Chicory Root or Chicory Root Extract is an additive or supplement to dog food. It can provide a range of health benefits including soluble fiber to enable regular passage of stool, probiotics to aid and promote digestion, as well as potentially eliminate or prevent intestinal worms. While these benefits are not fully proven, there is strong evidence behind them. The proportion of Chicory Root used in most dog food recipes is tiny and does not contribute meaningful nutrition.
