The object was delivered to Veterinary Faculty WULS in Warsaw for anatomopathological and radiography examinations. The X-ray examination demonstrated advanced irregular and radiolucent changes in the metacarpal and phalanxes area. The bone was augmented because of the strong, chronic reaction of tie periosteum.
