Drool aren't good choice for rotty's. Instead of that feed professional pedigree puppy food range. Puppy's fast growth period is until 6 months. Until 6 months you should provide good quality food including home base food like rice and boiled eggs, rice and curd , rice and dal pani etc. Feeding must be 4 times a day with 4 hours of gap in per meal. In this period the puppy is in critical growth periods. Almost 60% of growth is covered in 6 months of age. Rotty's are awesome just feed good quality food drools aren't good as I know rottweiler female I shared my perspective and experience of feeding food about rotty's.
