Foot Dragging

Question
I have a 6 year old lab who weights about 90# and recently he has started to drag his front right paw. I think he may have been bit by a bee about a week ago and I do not know if this could cause this action. I am worried about this, please let me know your thoughts.

Thanks
Steve

Answer
It sounds like a joint problem to me.  Overweight make such problems worse.  Few Labs should weight 90 pounds.  Check the guide at this link, and and adjust his chow and exercise if you need to.  http://www.puppychow.com/products/popup_body_condition.aspx
