awwww, conrgats on your pregnancy!!! We had our shepherd for a lil over a year when my son was born. What we were told to do by our trainer as well as our vet was to bring home a baby blanket with your new babys scent so your dog can get used to that first. Xaro(my dog) was fine with the new baby. We just let him sit by us when we held the baby and now after nine months he loves laying by him. Im not sure how it is with the smaller breeds though. Im sure everything will turn out well
again congrats on the baby!!!!!!!
