What are the symptoms?
CDM starts as a subtle weakness in one limb which might be misinterpreted as a chronic orthopaedic disease in the hip or knee.
You might notice your dog dragging their hind legs if they have CDM. They may start to fall when turning or when walking on slippery ground.
As the disease progresses they may develop a drunken walk within a few months. Eventually, it can affect their front limbs and make it impossible for them to support their own body weight.
