Okay, at 7 weeks the pup is an infant, it is a miracle that the pup can eat on it’s own, let alone walk. The pup pretty much needs 24/7 care.
The pup requires several small feedings of soft food a day, fresh water available and a splash added to meals.
At 12 weeks the pup should be out of the woods, for now, the pup is vulnerable to all kinds of problems.
Don’t expect housebreaking to begin for at least a few weeks…..
I would work closely with a veterinarian.
PS: If you are feeding kibble, presoak overnight in water.
