sequin style items to wear for the party

HELP. Bella has been acting very strange. She has been carrying a soft squeaky toy around in her mouth for two days and crying. Not crying all the time but if the toy ends up in the other room where the door is shut she cries and cries when she brings it to bed. She is eating find. No bathroom problems. No fever. She is just acting weird. I had a friend tell me her dog would do that when she was in heat. Like she was carrying a baby. She has not been fixed yet and this will be her second heat if that is what it is. I am going to get her fixed when my finances improve. She is current on her shots and I use all natural flea treatments. No fleas anyway. If it persist I am going to take her to the vet. But it seems to be a mental thing and not a physical thing. She is still playing. Very uncharacteristic of her. sequin style items to wear for the party
