Will a mother dog take in a rejected baby pup from another litter.
That really depends on the dog, and her capability to take care of the puppy. It wouldn't hurt to try!
It's not unheard of, so maybe
yes if it's still nursing age
If she has the room then most likely yes. Some even adopt a baby from a different species.
Possible. Mother animals will "adopt" babies of other species even, so it's definitely worth trying. Let mama dog sniff at the puppy before just leaving the puppy with her. She might accept it, might not.
Yes, I have even seen a mother dog adopt an orphan fawn!!!
It's possible. But sometimes, when a mother rejects a select puppy, that can mean there's something wrong with it.
That sounds adorable and yes, if she has room.
I've seen something like that once at a pet store. So yeah I'd say so.
