You said Rowdy does not seem to be in any pain, I would take him to a vet to make sure that he is ok. Hugs to Rowdy.
One of my friends dog had similar symtoms except her dog had pain as well and this is what it was.
Panosteitis which is basically a kind of growing pains - Here is some info on it.
Panosteitis: This disorder occurs when the normal process of bone degeneration and resorption fails to occur. As a result, there is an excess formation and thickening of bone. This condition most commonly affects the long bones of either the front (humerus) or hind (femur or tibia) limbs. Males have a higher risk than females for panosteitis.
Age of onset: 4-18 months
Cause: The inflammatory process responsible for panosteitis is poorly understood, however, overnutrition and rapid growth are factors widely accepted as playing roles in the development of this disorder.
Symptoms: Panosteitis is characterized by a sudden onset of intermittent lameness that may last for a few days or several weeks with the possibility of recurrence throughout cycles of growth. The lameness may be mild to moderate, may shift from one limb to another, and is unaffected by rest or exercise. Applying pressure to the bone-shaft of the affected limb usually produces an evident pain response. Lethargy and loss of appetite may also occur. In dogs with frequent recurrence or persistence of symptoms, there may be muscle atrophy of the affected limb.
Diagnosis: Radiographic evidence of panosteitis will be absent in early or mild cases of the disorder. In more advanced or moderate cases, areas of increased bone density within the shaft of the affected bone will be evident on x-ray.
Treatment: Corticosteroids, buffered-aspirin or non-steroidal anti-inflammatories may be used to reduce pain but have not otherwise been reported to noticeably influence the course or outcome of the disease.
Prognosis: Panosteitis resolves itself and symptoms usually cease by the time the dog reaches 18-24 months of age. |
