You know a couple of years ago, Oreo couldn't get up on the furniture anymore, couldn't jump into the car or make it around the block walking. Then we got the younger dogs and they seemed to lift her spirits and get her "youth" back.

It probably wouldn't hurt to take him to the vet and found out if something is wrong but it may be something that happens for awhile and then goes away. Simba certainly isn't old and he certainly has a lot more good years ahead of him.

Or you could tell your parents that a new pup would help make Simba find his youth again

And I am sure that dogs know we love them. This is the second time in six months that I have left mine for at least a week and they all just are excited and happy to see me and act like they knew I would be back and happy to see them too! They are all clamoring for the closest spot to me.
