In this situation, the stress to the joint surface is not even and can cause some form of osteochondrosis in the elbow when the puppy grows or make already existing elbow dysplasia even worse. Some of the breeds that are susceptible to that are for example Dachshunds, Corgis, Pugs, Bulldogs, and Beagles. Signs and symptoms
These conditions nearly all present with an insidious onset of pain referred to the location of the bony damage. Some, notably Kienbocks disease of the wrist, may involve considerable swelling, and Legg-Calvé-Perthes disease of the hip causes the victim to limp. The spinal form, Scheuermanns disease, may cause bending, or kyphosis of the upper spine, giving a "hunch-back" appearance. Symptoms in animals
The most common symptoms are lameness and pain in the affected joints. Animals may try to ease the pain and walk differently and the pain can be noticed by the change in animals walking style. The condition affects both sides (right and left leg). On most occasions, the other leg is worse. This can result that the dog starts encumbering the other leg and the healthier leg becomes more strained. Sometimes the symptoms are so mild or there are no symptoms which can make it hard to detect that there is something wrong with that dog. Cause
The ultimate cause for these conditions is unknown, but the most commonly cited cause factors are rapid growth, heredity, trauma (or overuse), anatomic conformation,  and dietary imbalances; however, only anatomic conformation and heredity are well supported by scientific literature.
Osteochondrosis is a family of orthopedic diseases of the joint that occur in children, adolescents and rapidly growing animals, particularly pigs, horses, dogs, and broiler chickens. They are characterized by interruption of the blood supply of a bone, in particular to the epiphysis, followed by localized bony necrosis, and later, regrowth of the bone. This disorder is defined as a focal disturbance of endochondral ossification and is regarded as having a multifactorial cause, so no one thing accounts for all aspects of this disease.Osteochondrosis is a developmental disease. It usually occurs in an early stage of life. It has personified features as focal chondronecrosis and confinement of growth cartilage due to a failing of endochondral ossification. Fissures can develop from lesions over the top articular cartilage and form a cartilage flap and an osteochondral fragment. It is diagnosed as osteochondritis dissecans. In animals
In dogs osteochondrosis is seen in elbow, shoulder, knee, and ankle joints. Elbow osteochondrosis is also known as "elbow dysplasia". There are three types of elbow dysplasia:  fragmented medial coronoid process, ununited anconeal process and Osteochondritis dissecans of the medial humeral condyle. Breeds that have the predisposition to these are Basset Hound, Labrador, Golden Retriever, and Rottweiler. Other breeds can also be diagnosed with this condition but it is not common.One of the leading factors to some elbow osteochondrosis is that the radius and ulna are growing at different rates.
