Chihuahua puppies

I just wanted to ask a question, well to anyone who will answer. I have been around several Brussel Griffons Females that are in heat and who are expecting. Does anyone else think that they act a little cooky. I think it may have to do with the changes in the body. Send me an email if you have ever noticed this in your griffy? FYI My Pippi is expecting her first litter in the middle of August. I am soooo excited about have my first litter of griffy puppies. Altough I have been around and help raise litters this is my own babies first litter.  i will post pics of them as soon as possible. I breed her to my gimli. He is one sweet little man
