How to deal with matted fur in dogs without causing pain or stress?

For mildly matted fur, use a detangling spray and a wide-toothed comb to gently work through the mats. Start at the edges and work your way inward. For severe mats, it's best to consult a professional groomer or vet, as cutting the mats out can risk cutting the skin. Regular grooming prevents mats from forming.
