Back when my MIL bred Mallorquin rater pups (a toy breed of the island), she kept two female pups from her last litter, and they nursed right up until almost 10 weeks old.
The momma will wean them herself and donŽt worry, sheŽll teach them to leave her alone once she feels sheŽs done
I remember feeling so bad for her too.SheŽd be sitting resting and suddenly her pups would come along, literally charge at her and then dive right in.Sometimes sheŽd even yelp! (sometimes theyŽd knock her over too).
Eventually she started nipping/growling at them and they understood momma
Sometimes youŽll want to step in, but believe me, dogs are FANTASTIC mothers (animals in general are fastinating with thier young).
They could teach
us a thing or two
