I had the opposite with my pups they were a bit constipated.. and id definately prefer runny poos at least they are getting out of their system haha!! I wouldnt worry if they are feeding and seem fine.. and if the vet is happy then thats ok...
puppies tend to have runny poos at first.. and the change to bottle feeding would have messed with their tummies even more.. so mums milk is definately best. :)
as i said i wouldnt rush into any more medication yet, just observe for now, check they are not dehidrated (pinch back of neck) and that they are feeding.. and your good to go
