I think that dogs do that when they have the "affectionate" trait and want/need attention. I've had it happen to my dogs quite a bit. My cats too! I also think they have to have a high relationship level for that to happen.
Zeus was the first one to be born......if you want this family, I can upload.....however, it comes with a Siamese cat named Jade, Maggie Hart (maiden name Bearington), Jewel, Zoey, Charlie Hart, Jasmine, and Bear too.........I dont want to split them up.
Cool! Not in game just yet, but I'll upload this crazy household (seriously.....taking care of 5 dogs AND a cat....plus humans? WOW) to the gallery and let you know my name in said gallery. That way you can not only get this fam, but take a look at the other stuff there too.
Just read that Jim Nabors has died. For those of you too young to know, he was an actor on 'The Andy Griffith Show' playing Gomer Pyle. His singing voice astounded you because it was nothing like his speaking voice. RIP Jim :`(
