Orijen Large Breed Puppy, if you can get it. There might be some trouble with supply, tho, becuase of the fire. I pretty well always suggest Orijen or Acana. Natures Variety has a large breed puppy, but I believe it has grain.
Look below in the signature and use the Dogfoodadvisor site. They have foods listed in different catagories and are easy to look up what particular type of food you need. I would get a 4 or 5 star food.
You can feed either a large breed or all life stages food plus the raw if great. I would probably cut back to twice a day at her age.
Sorry but I don't agree with this assessment at all. Tons of Dobes on this site(mine included) did absolutely awful on Orijen. I started on Orijen(5 star food), moved to another 5 star, then another... then another... then a 4 star... and a 3... and she does better on the "3 star rated" than anything else. I've poured thousands of dollars into vet bills, analysis at labs, allergy tests etc for this dog and I've come to a very basic conclusion about dog food. It's all crap.
Orijen VS Blue Buffalo, Wendys VS McDonalds in all honesty. One may be better but it's still crap. There are some people's Dobes on Purina and they looked a hell of a lot better than mine did on Orijen. Buy what works for your dog, don't be a snob(like I was) and try to force something that isn't going to work for them. You will regret it.
If you don't want to put garbage into the dog and that's why you want to avoid Purina/Iams etc(I know I do), think about Raw, home cooking, or something else where you can see what is going into your dog. Been 2 weeks since I took my dog off kibble for good and all bumps are gone, she looks a million times better, stool quality improved, no gas, putting on weight etc. I don't know what it was but kibble just didn't agree with her. Is it a pain int he ass? Yes, but watching her nubber swing back and forth uncontrollable at every meal time makes it all worth it.
