Pets( part 1)

I have taken lots of psychology classes over the last few years, and even though I am graduating this spring :] there are still more I wish I had the time to take. There is one class that I would like to take that just doesn't exist at USU. I would like a class on PET PSYCHOLOGY! There are many times I really wonder what in the heck(if anything) is going on in the head of my cat or dog.
I watched the movie "Up" with my daughter last weekend and laughed at the dogs on the movie that wear collars that speak what the dogs are thinking, and wished I had one of those collars for Lucy. I think it might be comical to find out what she is thinking. She still sings for us when we come home, and we have added a few more items to her bag of tricks. She now also "talks" on command. If I say "talk to me" or ask her "do you like popcorn?" She will say what sounds like "num, num, num." She will also stands up on her hind legs and turn in a circle (dancing.)
Lucy loves to play with toys. She has several small beannie animals that she carries around the house. She begs us to throw them so she can play fetch. Her favorite toy is a squeaky bear. She will play fetch with it also but she seems to have a ball carrying it around in her mouth squeaking it or rolling around on the floor with it. I think she might have a sense of humor because she can be a real tease. She will bring a toy to me and touch it to my hand and then pull it away before I can grab it. She will do this several times and then drop the toy at my feet so I can throw it for her. I would love to know what this pup is thinking!
