However, there are young dogs, aged between 5 and 18 months (most often males) which suffer from a relatively common disease - "panosteitis" (inflammation of the bone tissue). Perhaps it is related to rapid growth of the affected dog. This disease occurs for example common in German shepherd dogs, but our Otterhound is also a candidate for this problem.

For the dog, panosteitis is painful and therefore
expressed in lameness. Fortunately, the disease heals spontaneously, mostly all by itself. To help the healing in any case the should be immobilised as much as possible, also he should be prescribed additional anti-inflammatory drugs by the veterinary surgeon depending on the severity of the disease.
Of course you will have to consult your vet in this case as self-diagnoses can be dangerous ... But you should indicate to your veterinarian that the breed is prone to panosteitis.
