my rottie pup is 4 weeks old and not walking yet what should i do?
At 4 weeks old, your pup should be walking and running around, even if a bit clumsily.
If he’s not doing that then he needs to be evaluated by a veterinarian as there could be some sort of health issue that is slowing down, or preventing, him from walking.
The sooner something is recognized and dealt with, the better, so please get him to your vet asap. Best of luck, hope he’s running around soon.
