My dog puts her toys togeather and crys?

1st question I have to ask is is she spayed, if not does she do this at certain times in her cycle? It sounds to me like, as you say, her maternal instinct is very strong and she views these toys as litter mates, hence the extreme happiness that they are all tucked up and safe! Some dogs do this even when they're not spayed anyway. As long as she's happy I wouldn't worry, ..sounds like she has an owner who understands her needs completely ! Bless her, she sounds adorable !!
