Slow Lazy Response to "Come" command

[Ricki and Tara (doodle)]

Maybe I shouldn't complain because Tara pretty much always responds to "come" around our property. HOWEVER, she doesn't respond instantly. For instance in the house, if I call her, she will stand up, do a BIG stretch, YAWN, then SLOWLY walk over to me like she is about 100 years old (she isn't 2 yet and has no physical issues in this regard).

 

Outside in the yard, she will turn to look at me, then turn away and sniff something and then look back at me and USUALLY will come running.  But sometimes she won't start toward me until  I begin to take one step toward her. As soon as she sees me start toward her she is ON IT and SO happy to come to me!! But I am not getting an immediate, snappy response. It is almost like she is considering her options. 

 

Does anyone else have this issue? I am not sure quite what to do as she IS responding. How do you tell a dog to hurry up? Should I respond to this as I would if she didn't come at all? That doesn't seem quite right either so I haven't done anything.

 

Any ideas?

When I changed the "come" command to "treat", my dogs started moving a lot faster!!

Ha! That's good! And what do they do if you don't HAVE a treat to give them?? :)
