Well I won't tell U it will end after she whelps her puppies cause it didn't end with Tiffanies' last litter, she got worse, she really never went after our males while she was pregnant...But she had 6 with her last litter and we also just adopted Sage and we had 10 Yorkies at that time so it could of been a combo of all of the above. So I don't know if it was all the above or just her harmones not adjusting right after whelping...I'd keep them seperate till after she whelps and not let either dog around her or her puppies for U think she's after them now look out after she whelps and has newborns, they are more protective then. I wait till our babies are around 6 weeks old before I allow daddy to see our puppies. Just my OPO tho
