Sad Puppy

Question
I have a pitbull that is 3 years old she is not your normal dog i would say, anyway sometimes she will get really sad she has a bunch of toys that we call her babies and sometimes she will take them all (7) with her where she goes or she has to sleep with them and if you take them from her she starts to cry she keeps that up until she finds it and brings it back with the other ones so i guess I'm asking does she want to be a mom? or what could it be?

Answer
If she is not spayed,it may be something called a fake pregnancy,and one of the symptoms is them trying to suckle toys,since they didn't have any real puppies,and the best cure for this is the get her spayed

and sometimes it means the dog may have had puppies in the past,and something may have happened to them such as they died or were taken away too soon

And if it's not either of these,sometimes they just do it for comfort,it makes it feel like other animals are around them-and she may want to try and get your attention to play with her more often
