Hi thanks for the reply. Well the wee one was in today and what a cutie. The vet showed me the xrays and it is quite extreme. The sternum is short and to vertical so no where near the ribcage, the diaphgram is in tact but pushed forward as is the liver and the heart is lower down than normal and a bit squashed as are the lungs. Dont know if this is a common thing in cockers but the vet definately things although congenital definately hereditary as well
