Answer: border collie puppies wont eat
I just answered a similar question below. As suggested, try changing the environment as to when and how they have their meals. Secondly, as they are working dogs - try taking them out for a big run or walk before dinner time so they can work up a appetite. If you add a egg yolk to their meal, it might help them to bulk up a little.
