It is always advisable to consult with a veterinarian before combining any treatments or dietary changes for your pet. While Red Coat food is hypoallergenic, balanced, and designed to improve coat color naturally, it's important to ensure that it does not interfere with any other treatments your pet may be receiving. A vet can provide guidance on the appropriate course of action and whether combining Red Coat food with other treatments is safe and effective for your pet's specific needs.
