Hi  there, my bitch is now at 57 days, i took her for a short walk yesterday and she produced 2 small bright yellow poos,i have just taken her for a little walk up the track up again and she has just produced 2 more small normal coloured runny poos she seems happy enough though slightly off her food the last couple of days...is this (in particular the yellow poo) normal.

She is clearing her bowel ready for whelping

Excellent, she has also just lost her mucus plug this morning and was digging in her armchair in the middle of the night so looks like things may be progressing !!
 

Hope all goes well
