Puppies should be allowed to nurse with their mothers atleast until they are 6-8 weeks old. After 8 weeks they would be healthy enough to find themselves a new home.
No, most likely, you got your puppy around 7 or 8 wks. If you got your puppy earlier than that, you really should not have, because it is too early to be taken away from it's mother. But if your puppy is only 11 wks, it probably has not been with you that long, or really devolped a special bond, so it should transistion into a new home smoothley. Good luck finding your puppy a new home!
It can if you clean it good enough
To show dominance.
When you bring the puppy inside let him/her smell every room,go with it while its checking things out.In just a few days the puppy should be comfortable enough to go from room to room on its own.
a month
The puppy should be 6 weeks old.
a puppy wormer
Leave him at home while you walk the big dog and play with the puppy at home.
No puppy should be taken away from its Dam and litter mates before it is 7 weeks old. They learn a significant amount about how to interact with other dogs in that time which they can't learn if they are not with their litter mates and mother.
it depends on how often you use its name, what kind of dog it is, how old it is and so on. so the answer can verry. if it is a young intelligent puppy than it shouldn't take very long.
No, I do not believe that you can get a puppy that is 3 weeks old. As far as I know, the puppy of any breed has to be at least 6 weeks old in order to take it home. Sorry if this answer is disappointing, but the puppy has to stay with its mother for that long.
Yes, of course you should install smoke alarms in the new home you are building. Smoke alarms should be in every home , old and new.
