Mom may be producing more milk than you think. When the puppies are getting some of Mom's milk and not hungry enough, then they notice the difference in taste , prefer the mom milk and may not want the other milk.
If you have a scale that measures in metric you can weigh them record their weights and 3 hours later see if they have gained or maintained their weight just on Moms milk.
If they have then just continue to weigh and not supplement as often..go 6 hrs or more and they will take it if not getting enough and they are hungry. |
