My dog is roughly 1 year old, male and he has been playful and energetic. Now when we try to get him to play he doesn't seem like he wants to. Could this be related to joint health? If not, what could possibly be the problem. He has been having some problems with his pancreas and were not quite sure if this is related to the problem or not.
Weather changes can have an affect on a pet's activity level as can changes in the household routine. If his health is fine, it might be that he has outgrown the puppy playfulness so you might have spend more time engaging him in play time. Does he have a favorite toy or game! I find it helpful to schedule time to play with my pets each day. They come to expect it and it really helps with bonding too. Good luck!
