It's me again!

So Buddy got neutered on Friday the 23rd. He has been healing up great! We have had to keep his cone on about 90% of the time because he is very eager to lick his stiches. We were told, "no running, jumping, stairs, barking or strenuous activity for 2 weeks".... hahahaha. We have tried! We have given him kongs to try to mentally exhaust him, but it seems he has soo much pent up energy now that we have cut his activities down.

Are there any safe activities for him to help burn some of this energy off? Anytime we take his cone off it is like we are living with the energizer bunny!
