Tartar build-up on your dog's teeth not only affects their appearance but can also impact on their wellbeing. After your dog finishes eating, bacteria will settle on the teeth resulting in a soft film called plaque. If this is not regularly removed, over time calcium which is naturally found in saliva will stick to the plaque turning it in to tartar also known as dental calculus. Once formed tartar cannot be removed by tooth brush or chewing and requires a scale and polish under veterinary supervision. Royal Canin Dental Care Medium kibble has a specific size shape and texture to encourage crunching and to provide a tooth brushing effect with each meal. Calcium chelators included in the kibble coating 'trap' calcium, helping limit tartar formulation. Royal Canin Dental Care is available as dry kibble. Please follow the feeding guidelines based on your dog's ideal adult bodyweight. Suitable for adult medium breed dogs (11-25kg) to help maintain dental health - complete nutrition balanced for long term feeding.
