Imprinting Dogs

Ilonka • I'm a first time mom with my baby boy born on May 2nd, 2016.
We have 3 dogs, all husky or husky mixes and I have seen that they choose their owners and imprint on their human. My husband and I both have our own dog that favors us and that leaves poor little Yukio without being imprinted. 
The bigger I get the more he cuddles me and I feel like he is attached to the unborn child in the family.
Far fetched I know but can a dog imprint on an unborn human? Maybe he knows our son will be the best of both worlds, my husband and myself. ( I'm 25 weeks and 3 days now)
