I am beginning to think Keana is either not pregnant or is only having one puppy. She hasn't gained any weight in a couple weeks now and her nipples still look normal. Isis on the other hand has been looking very pregnant for the last month. I am planning on getting a x ray done on Keana in about a week to determine IF she is pregnant and if so how many she is going to have. I have never had a pregnant pug before but I'm pretty sure she should be looking pregnant by now.
