Good morning Rochelle, I am sorry for the delay in response I was offline by the time you came back.
In response to your question, there are many possible reasons that would cause weakness in the back legs of an older dog. A very common cause is arthritis of the hips; other possible causes are: A pinched nerve along the back as a result of a bulging disc or even weakness secondary to a systemic disease.
To determine the exact underlying cause he will need a hands on examination by family veterinarian, xrays and blood work as initial screening test. If it is concluded that this is related to arthritis of the hips he will benefit from being placed long term on arthritis medication like rimadyl. In the meantime, you can begin to supplement with Cosequin (glucosamine) long term; this supplement helps by promoting the production of joint fluid. You can buy cosequin online, vet's office or your local pet store.
