Weird Thing Happens While My Dog is Nursing

So this this weird thing happened while my dog was nursing, which happens everytime. What happens is that when the pupps come to the nipple, for like few minutes the bite and pull and pull and pull. And then something happens they all just stop pulling and start sucking, since this is the first time i saw that i had to make a video on it, it smost likely normal but as i havent researched it, to me its weird. Let me know what you think, comment down below! Im new to vlogging so be patient with my amateur videos, i learn as i go along. The latest videos are looking much better than the older ones so it means im on a good track. What would also be good in helping me get better is constructive criticism! thats right, i do not mind to hear what you liked, disliked and what i can do to make things better... you get the picture, So dont shy away and lay it all out! ---------------------------------------------- # Dog Names # -Boys- Puffy - Doty, Zoro, Ticy Not Puffy - Slim, Simba, Tripps -Girls- Ringa, Jeydi, Maili ---------------------------------------------- - SOCIAL PROFILES - # INSTAGRAM @TheHuskyFamily # https://www.instagram.com/thehuskyfamily/ # FACEBOOK @TheFamilyOf9Huskys # https://www.facebook.com/TheFamilyof9huskys/ # TUMBLR @TheHuskyFamily # https://thehuskyfamily.tumblr.com # TWITTER @TheHuskyFamily # https://twitter.com/TheHuskyFamily ---------------------------------------------
