when to give my 7 month old adult food

Question
I have a 7 month old english mastiff. We are starting her on Eukanuba large breed puppy food. I am wondering when I should start giving her adult large breed food

Answer
Hopefully I caught you before you started her on the Eukanuba.
Go to a pet store and choose a food with 23 percent or less protein, no by products,no corn, wheat or soy. Try something like FLint River, Wellness or Natural Balance. Eagle Pack is excellent also and makes a great large breed puppy. They're pricier but in the end because they contain no fillers, which the dogs just poop out anyway, they eat less for more nutrition and cost less per day to feed. If you can't find a large breed puppy with less than 23 percent protein,. then stick with a good adult food from one of the brands mentioned.
Watch your baby for pano. :) And enjoy
