The diseases more especially meet for the labrador are the hip and elbow dysplasie
Our dogs have been x-rayed and we only breed with dogs who are free of hip- and elbowdysplasie. You must now that the hips and elbows dysplasie are not only hereditary problems but can also come with environemental conditions such as a dog carrying too much weight, puppy doing too much exercices (he must play and run at his own rhythm). No jogging with you before that he has finished his growth.
A food of good quality is also very important and will contribute to an harmonious growth of the puppies.
