Hi, I am new to this site and have some questions. Hopefully you will have some answers for me. I have an American Staffordshire and mated her a few weeks ago..I am new to this tooo. She now seems extremely tired, and her eating habits are different , as in her choices of foods..she isn't as playful as she used to be. I am not sure she is pregnant and would love any info on this you may have. Thanks in advance!!
