Joints are complex structures that enable the body to move, stretch, bend and rotate. Nourishment is delivered to the joint via joint fluid, which helps lubricate the joint for ease of movement.
By design, joints rely upon an intricate balance of strength, flexibility and lubrication for proper range of motion and are continually employed during periods of both rest and activity.
Complete and balanced nutrition ensures each component of the joint’s anatomy receives the right nutrients necessary to execute normal cell regeneration and metabolic processes.
Glucosamine and chondroitin are molecules that are part of the structure of cartilage in joints. The body can either make these from other nutrients or use what is provided in the diet through ingredients that contain some cartilage components.
Glucosamine is a small carbohydrate molecule that is rapidly and almost completely absorbed from the gastrointestinal tract in dogs.
Chondrocytes (cartilage cells) can make glucosamine from glucose (a sugar) and glutamine (an amino acid), but this is a rate-limiting step and can delay the production of larger structural molecules in cartilage. Therefore, a dietary supply of glucosamine can be important at times of high demand.
Chondroitin sulfates are pre-formed structural molecules and stimulate cartilage production by providing necessary building blocks. Chondroitin sulfates are large molecules and the fate of dietary chondroitin sulfate is less predictable than that of glucosamine, as digestion will break down some of the chondroitin before absorption.
In addition to glucosamine and chondroitin, the diet can provide other nutrients important in cartilage structure, including glutamine, sulfur-containing amino acids and glucose.
The levels of glucosamine and chondroitin in our healthy and natural dog food are intended to maintain the nutrient balance of healthy joints.
Joints are active tissues, and old cartilage is constantly being broken down and replaced by new cartilage. The levels of glucosamine and chondroitin provided by our dog food support the natural turnover and daily rejuvenation of cartilage.
Glucosamine and chondroitin in dog food are not intended to recover the health of joints that have been damaged through arthritis. This would require far more than could be delivered in pet food, and the research to support such a benefit is unclear.
Studies using high levels of glucosamine and chondroitin supplementation in dogs have resulted in both no effect and positive effects on joint health1 2, meaning that these high levels may or may not have a beneficial effect on joint health.
These studies used doses of 1000–1500 mg glucosamine hydrochloride and 800–1200 mg chondroitin sulfate for 20–40 kg dogs. For a typical dog, food would need 2,300–3,850 mg/kg glucosamine and 1,860–3,115 mg/kg chondroitin depending on dog size to get similar daily amounts in these studies. These levels far exceed current inclusion in dog food formulas, which are typically less than 1,000 mg/kg.
Glucosamine and chondroitin come from natural ingredients such as meat and meat meal. We use chicken, lamb, salmon, chicken meal, lamb meal and fish meal in our healthy and natural dog food. Typically, any product containing these ingredients will have certain levels of glucosamine and chondroitin already naturally present. We add glucosamine hydrochloride and chondroitin sulfate to help support health joints.
New Zealand green mussels (NZGM) provide the nutrition to help nourish healthy joints and promote general mobility.
NZGM contains a unique profile of omega-3 fatty acids not found in any other species, including high levels of eicosatetraenoic acid (ETA), which is an intermediate in the metabolism of ALA to EPA. Nutrients supplied by NZGM include:
Together, these components provide the necessary nutrients for healthy joints.
NZGM – New Zealand green mussels
ETA – Eicosatetraenoic acid
ALA – Alpha-linolenic acid
EPA – Eicosapentaenoic acid
DHA – Docosahexaenoic acid
Added glucosamine and chondroitin help maintain joint health.
An optimal combination of natural ingredients that provide an excellent source of essential vitamins and minerals. Ingredients such as white fish and eggs provide high quality protein and are blended with high-quality natural ingredients such as brown rice, barley and sweet potatoes to provide the right balance of carbohydrates.
Foods with a limited protein source may be beneficial for pets with food sensitivities. A limited protein source pet food uses a minimal amount of protein sources.
Omega-3 and omega-6 fatty acids from fish oil and canola oil help maintain skin and coat health.
Contains 9% fewer calories than our Vetdiet® adult large breed dog food. High-quality protein from deboned chicken and added natural fiber from ingredients such as peas and whole barley contribute to a feeling of fullness and help achieve a healthy weight.
Omega-3 fatty acids from flaxseed and fish oil help maintain skin and coat health.
Added prebiotics help support digestive health.
