Poodles are generally considered a healthy breed and have a balanced diet when fed high-quality commercial dog food that is appropriate for their age, size, and activity level. However, in some cases, additional supplements may be needed to ensure optimal health and wellness.

1. Omega-3 Fatty Acids: These can help improve skin and coat health, as well as joint health and mobility. Fish oil is a good source of omega-3 fatty acids.
2. Glucosamine: This is a natural substance that helps maintain the health of joints and connective tissues. It can be especially helpful for senior dogs or dogs with joint issues.
3. Probiotics: These can help maintain a healthy digestive system, boost the immune system, and improve overall health. They can be found in yogurt, kefir, and some commercial dog food.
4. Vitamin E: This is an antioxidant that can help protect against cellular damage, support skin and coat health, and boost the immune system.
5. Calcium: This is important for strong bones, especially in growing puppies. A calcium supplement can be added to the diet if the dog food does not provide enough.
6. Vitamin B Complex: This group of vitamins helps maintain energy levels, support a healthy nervous system, and improve the overall health of the skin, coat, and eyes.

It is important to speak with a veterinarian before adding any supplements to a dog’s diet. They can advise on the appropriate type and dose of any necessary supplements based on the individual dog’s needs. Over-supplementing can cause health problems and interfere with the balance of nutrients in the diet.
