My Bruin is stiff too when he gets up and most of the time doesn't want to get up. I know whatever the reason it can't be too bad because he can certainly haul 'arse' back inside the house when he's done with his business. I have been going back and forth about giving a supplement. I'm considering a multivitamin with added glucosamine. Glucosamine helps with their joints. I'm sure others will be along to help soon.
