Overview
Caution. Copper proteinate is safe in trace amounts. It’s a highly absorbable copper source important for enzymatic function. However, excessive consumption can cause copper storage disease, especially in predisposed dog breeds.
Can dogs eat Copper Proteinate?
Benefits
- Copper proteinate is a type of copper chelate where copper is attached to proteins or amino acids. It has a higher absorption rate than inorganic forms of copper, such as copper oxide and copper sulfate. It's used both in animal feed and human supplements.
- Copper proteinate is important in the formation of hemoglobin that helps in carrying oxygen to the body tissues. It also helps in the absorption and metabolism of iron to prevent anaemia.
- Copper supplements play a role in the synthesis of collagen and elastin, two proteins that are important for the skin, joints and blood vessels.
Risks
- Excessive intake of copper proteinate can result in copper-associated hepatopathy (also known as copper storage disease), where copper deposits accumulate in the liver, potentially causing liver damage.
- There is a high risk of developing a copper-associated hepatopathy in dog breeds that have genetic predisposition to copper accumulation. Affected breeds include Bedlington Terriers, Doberman Pinschers, Labrador Retrievers, West Highland White Terriers, and Skye Terriers.
Servings
- Copper proteinate is usually added in some commercial dog food brands as part of the mineral premix.
- The current minimim recommendation of the Association of American Feed Control Officials (AAFCO) for adult dogs is 1.83 mg/1,000 kcal mg/kg. However, many commercial dog food formulations have higher amounts of copper, exceeding the minimum recommendation, ranging from 6 to 10 mg per 1000 kcal. While this is considered safe for most dogs, it may be hazardous for sensitive breeds.
- Copper proteinate supplements formulated for human use may contain higher concentrations that may not be safe for dogs. Copper supplements should only be used under the guidance of a veterinarian and must be specifically formulated for canine use.
