Ehlers-danlos syndrome in dogs, also known as Dermatosparaxis or cutaneous asthenia is a conditions where the skin is extremely stretchy or elastic and also tears very easily. Over flexible joints as well as eye problems and bleeding under the skin can be seen. The skin can split up the middle of the dog’s body starting at the tail and moving upwards which can lead to dogs being put to sleep as it doesn’t heal well or at all.
