Do you free fed or go on schedule?
If it has been going on for a few weeks and they aren't losing any weight and seem to be acting normal then I wouldn't worry to much about it, they are getting older and the younger the pup in my experience the more they eat... always wondered if it had to do with fighting their litter mates for the food LOL
At any rate if you are worried you can always give a little extra's, cottage cheese is a nice treat .. and don't forget with these tiny ones if you are giving treats in between meals they fill up easy |
