Chest very deep. Breast wide. Back rather long than short. Loins arched. Belly well drawn up.
Body - Great depth and spring of rib is very important as it gives lung and heart room. A shallow chest that does not reach down to the elbow is very unsightly and completely spoils the underline of the body. The shallow rib cage often compensates with width and giving a barrel chest. Some experts say this gives greater capacity to lung and heart, but I have been told by heart specialists, a deep chest is the best and that is what our Standard shows to be correct. Betty Murphy, in her book on the breed, describes the chest, if bisected at right angles to the spinal column, as egg shaped. A very apt description. The breast should be wide, a generous hand's width between the elbows, and plenty between the point of the shoulders, coming well forward as opposed to sinking back to form a hollow chest.
Long rather than short. Loins arched. Some people find the first part of this statement to be the vague part of the standard, but maybe it is where the eye and experience are most called upon in the interpretation of the Standard. Take the back to be the whole ribcage and loin, and starting just behind the shoulder, the back dips slightly then gently rises up and over the loins dropping down to the hip and further on down the croup. The ribcage should be long, carrying almost as far back as the arch of the loin. The loin should not be excessively long, about a hand span in length. It must be broad and very strong as it plays a major part in the propulsion at the gallop. That gives the length to the back - a long ribcage coupled with a moderately long loin. Length of rib cage, together with depth and spring is important, as a lot of vital organs are inside - lungs, heart, liver and stomach, if they have to be squashed into too small a space the performance of the hound would suffer. Too long a loin without a well ribbed up body will lead to weakness and probable flattening of the loin arch and so inhibiting galloping ability. The spinal column in a galloping hound must be flexible, particularly in the region of the loin. Faults in the topline, too sunken or hollow back, obviously a bad weakness, which would make movement difficult particularly at the gallop, where the spine has to flex up into a curve. A straight back would create similar problems and probably also carry a high tail, as the spine would not drop well enough down over the croup. Another fault I have noticed is the falling away topline. All the height is at the shoulder and it gradually, sometimes quiet steeply, drops away to the rear without proper undulations. Also, the roached back, which draws the hindquarters too far under the body and is accompanied by straight stifles.
Turning to the underline - We have already established that the ribs should be well sprung, deep and carried well back. Down at the brisket the ribs fit into the sternum or breastbone, which curves down from the front of the chest. By the time it reaches the elbow region it should straighten out and carry well back, almost to where the loin starts to arch up along the back. A short sternum means the ribs cut up too sharply, taking away from heart and lung room and generally spoils the underline and belly tuck-up. This is called herring gut.
Belly should be well drawn up - Muscles and correct weight control this factor and obviously a healthy, correctly fleshed, strong dog is what we want. No tuck-up is a fault, but very little body between loin and ground is also unattractive and could be an indication of a hound carrying too little weight.
