Supplements are called that because they are just an add-on to their diet. However, that does not mean your dogs would not gain more by making them a part of their daily nutritional intakes. Supplements can work in so many ways.
Some supplements are there to prevent a lot of health conditions. Some dogs are at risk for various diseases depending on their breed, age, and activity level. By giving them supplements, the possibility of them catching them would be lessened.
For example, puppies who take fish oil supplements will have enhanced cognitive functioning. Fish oil is also helpful in adult and senior dogs to maintain their mental alertness. And for those who are predisposed to some heart conditions, fish oil can also help prevent those.
Other supplements like L-tryptophan and alpha-capsazepine can relieve stress and anxiety in dogs. These help those undergoing stressful environments and situations like moving to a new place or some type of medical care. Vitamin E supplements boost the immune system's function to combat the different pathogens that your dogs might encounter.
Do consult your veterinary clinic Chesapeake, VA before starting your dog on any supplement.
