I would like to thank everyone for the replies, care and concern! I have learned in the past few hours after reading the replies and badgering my husband, that yes indeed, our female was found in our front yard one day when he returned home from work (he neglected to tell me this) and yes it was while she was in heat! My husband had let them out into the backyard in the morning and forgot to bring them inside!
!!!! So yes there is a GOOD chance they are not our male yorkies babies
..... First thing in the morning I will be calling our vet to get parental DNA testing and thankfully my mother, is willing to take in both puppies WITHOUT papers (I will not register them) when they are ready to be weaned, should they turn out NOT to be our males pups! I can only be thankful that our female "Miley" had a successful birth without any complications as it could have turned out so very badly for her!! I have attached photo's of our male "Indi", second photo is our female "Miley" and the third is a picture of the second born pup...I will also be sure to post the results of the DNA testing! Thank you everyone!
