I am currently hand rearing a litter of 8 labrador puppies. Very sadly at 2.5 weeks they had to be separated from their brilliant Mum on vets advise as she was very ill with erupted mastitis (horrific!).
They are now 4 weeks and after a shaky first well doing great and putting on weight well.
For the last few days after their last feed of the night they are play fighting but very roughly. There are often loud yelps. At the moment I am not physically intervening but clapping my hands and saying 'no' loudly which works... for a few seconds!
There are a few pups much larger than others but at the moment I am not seeing any more dominant or submissive than others- they seem to rotate roles. Which makes me think its just very rough play. Does anyone have any advice? Also any ideas why it happens just before their long night sleep?
