We have three dogs.  Cheddar, the dachshund retriever mutt belongs to my son,  Bleu the Beagle belongs to me, and Ruebenz the basset hound puppy belongs to my wife.

Bleu has been spending some time wearing a diaper and alternately hanging out in the dog cage.

Cheddar is the oldest and we have had her the longest.  She is fixed and doesn't need to wear a diaper nor go in a cage.

But for whatever crazy reason she has gotten a little jealous of the beagle and so whenever I leave the cage open, I find cheddar camping out in it laying on the Beagles blanket.
