First thing, get a vet check, including blood work, ear, fecal/urine testing for critters. Whining could be a sign he's uncomfortable or in pain.
If he gets a clean bill of health, enrich his life, give him a job to do learning new skills or hunting treats/toys hidden throughout the house couple times a day w/lots of happy praise when he finds each, increase walks, play with mommie/daddy time or play date at local pet store. Serve his meals in forage toys where he has to work to eat - dogs LOVE the concept. Pile small teddy bears or big stuffed animals or pillows on the floor for him to climb on and be sure you're close by to be sure he doesn't fall off. If he's not sick he's likely bored to tears and needs his life enriched with a job, interactive fun time.
