Does your little one show signs of thriving? Is his mouth warm like he is getting milk? Is he peeing and pooing? Are you weighing the babies to ensure they are gaining weight? I am glad you found a thread on the same subject.
Oh gosh, I was just re reading and they are already over a week old! Perhaps then the pups will get a little vet check soon and you will be able to get more information and make sure everyone is thriving. Good luck
