Our new dog, Nina, is scared and jealous of Elvis, our cat. Elvis just wants to play, but Nina’s having none of it!

I’ve never seen a dog so unwilling to play in my life. She doesn’t like toys and just ignores them. She doesn’t want to play fetch, tug-o-war, or even chew the toys. Elvis has tried in vain to get her to play with him, but she just avoids him or retreats to her bed. Mike and I got her to play with some bubbles a couple of nights ago, but she refused to even look at them last night.

The only thing that makes her smile is a walk. She loves to run in the park and is always surprised when the leash runs out of slack and she’s pulled back. She loves to smell every plant and post along the way.

How can it be that the only play she is interested in is a walk? Is this common?
