Anyone had a mom who carries her puppies around before eventually dropping it back with siblings? A different puppy each time. Not picking on any one puppy. Just carries one of them around sometimes for short time maybe up to a minute (which seems long)

She is otherwise good with them, feeding and cleaning them and they're happy and healthy and thriving.

When she takes notion of carrying one it's not so happy squeeling but she makes it happy again when she lies down with it. They're not getting hurt as in bleeding or visible hurt however I'm sure they don't like being carried about when they cry during being carried.

They are on tiles which are underfloor heated and bedding on top.. comfortably warm. Mom is clipped so she is comfortable too and she not panting or anything like that.

The puppies are 3 days old now.

Has anyone experienced this before?

Sorry but no, none of our bitches has done this.   Are you sure she's expelled all the birthing material.   Something is making her restless I'd suggest.   And is she somewhere well away from any other household pets because she may be feeling threatened, both she and her puppies?

Could be the mother is not too keen on he box, some like to be in a more covered den like place to feel secure.

One of our girls carried all her puppies from her all singing, all dancing whelping box with heat pad and heat lamp to our other dogs scruffy plastic box in the kitchen, I moved them all back and she did the same again. She eventually settled with them in the right place. This has happened on a couple of occasions with different girls, no issues with any of them so I wouldn't worry.

the only time I have heard of this is with a bitch with Eclampsia or when puppies are too hot.

If puppies are not restless then I would be worrying about the bitch having eclampsia, low calcium levels.

this can be very serious and life threatening left untreated.

Bitches can start to stare and carry pups and even kill them.

Bitches can be prescribed a supplement like Calo Cal D a liquid calcium and /vitamin D supplement, they have to be balanced to be absorbed.

If one of mine moved her pups I would right away know that she was unhappy.  The whelping box needs to be in a safe and quiet dark place.  Denlike, as someone has mentioned.  Bearing in mind that some whelps in my breed only weigh 2-3 ounces I would listen to my bitch.  (I totally realise that this could be breed dependent.)

I did smile at Lynne's post - I once had a bitch who didn't want to move to her whelping box until after the pups had been born.  She chose to have her pups almost underneath the radiator in the living room (the green patch never did wash out!)   The cream carpets had only been put down 3 weeks earlier.    

I did notice that you say the mum and puppies are on an underfloor heated area with bedding on top, if you don't have them in a "den like" box or covered crate then mum may feel that the babies are too exposed and she would like to hide them a bit more, it just makes them feel more secure, she is probably just a bit confused and will stop in a couple of days when she settles down.

I have always since my third litter made a den like whelping areas covered with a blanket.

I use puppy panels around and one on top.

Putting a table over an pen style box and draping a blanket over would do the same.
