Hi guest
You should be able to see on the packages, how much food the dog should have per meal.
I'm changing food for my girl, Luna, a choc lab puppy 10 months old today!! I know she should have 110 grams per meal from Eukanauba and about 175 grams of hills Natures best per meal. I change over a period of 10 days, with an increase and decrease of 10% a day. Today we are on 40% (44 grams) Eukanuba and 60% Hills (105 grams). I use adult food now, so your pup should probablely have a lot more.
I use Hills Natures Best, because I can't buy Burns, Arden Grange, JWB or Naturediet in Denmark. So I'll take the best of what I can get. The Eukanuba gave her gas. So it was either a change in food or buying a gasmask!
Good luck with your little one!
