Medicine
When an ingredient in dog food is said to be "medicinal", it usually means that this ingredient provides specific health benefits for the dog. These ingredients can come from natural sources or be specially developed supplements that aim to support or improve certain health conditions.
For example, certain herbs or botanicals may have anti-inflammatory properties that can be helpful for dogs with arthritis or skin problems. Omega-3 fatty acids found in fish oil support skin and coat health as well as cognitive function. Probiotics, found in some dog foods, promote healthy digestion and can boost immunity.
However, it is important to be careful when choosing dog food with medicinal properties. Not every ingredient is suitable for every dog, and some may be counterproductive if there are pre-existing health problems or allergies. It is always advisable to speak to a vet before introducing any new foods or supplements to ensure they are suitable for your dog's individual needs and health conditions.
