I have a 12 year old lab who has in the last day started whimpering when he moves. I do not recall any falls or strenuous walk. He is an inside dog and doesn't get much exercise. He goes to the vet yearly and has not had any major problems...slight arthritis in hips and has a ligament strain that healed on its own.

He currently eats a senior food with glucosamine in it. He also get a glucosamine supplement.

He weighs 100lbs but is not overly fat. His stomach goes in and not out past his ribs.

I have have been home with him today and he has pretty much slept all day.

I was was thinking about trying to take him on a short walk everyday to get some excersises and just get him up and moving. Though maybe he is just getting stiff?

any thoughts?
