Musladin-Lueke Syndrome, MLS
This condition causes abnormally strong connections between the structural proteins that provide strength and integrity to tissues like the skin and skeletal muscle, as well as the protective tissue sheaths of the bones and central nervous system.

Signs and symptoms
Dogs with MLS typically come to the vet because of severely contracted joints that cause them to walk on their toes, rather than their paw pads. However, due to the effect of the mutation on internal connective tissues, some dogs can also experience seizures.
Signs are often first recognized in puppies.Uncover health risks with Embark

What to do if your dog is at risk
Actions
- Talk to your vet about your dog’s MLS result so you can plan appropriate care and monitoring.
- Provide a calm environment and avoid strenuous exercise or rough play that could strain tight muscles or joints.
- Keep your dog’s living space safe with rugs or mats for traction and soft bedding for comfort.
- The severity of this condition can vary. Some dogs live comfortably with mild stiffness, while others may develop more serious complications. Work closely with your vet to help your dog stay relaxed, mobile, and engaged in daily life.
