after breeding

Question
my 2 and a half year old yorkie cross poodle has had 3 pup's there 5 weeks old now but mum has started to bleed again, and loosing alot of weight, hardley eating and has stoped feeding the pup's. should I be worried about her or is this normal? she also has reverted to weeing anywhere in the home like being a puppy again herself, this bit i know is not normal it's like i have to retrain her. what can you suggest?  

Answer
Was she given a shot of oxytoxin after she whelped her litter?  And where all the placenta's accounted for?

Could be that she retained a placenta, or even a pup which could be causing an infection.  

I would take her to your vet and have her checked out immediately.

Good luck.
