Word of warning about Eden, its a very good quality food and lots of dogs do very well on it, but if you Google you will also find a lot of people have issues with the food and loose stools.
We tried to get ddog onto Eden from around 14 weeks, we had awful loose stools that we embarrassingly couldn't pick up and smelly wind. We phoned them and tried their advice for months, we were told his body was detoxing from previous food, to try elm tree bark, canikur probiotic paste, a slow feeder as he was eating it too quickly 
, to feed less, to feed more, and basically keep trying. We were a bit naïve in thinking we had to give the pup these things.
2-3 days after giving up and switching to Millies Wolfheart I brought a poo bag home to show dh it was so lovely and small and firm 
and the smelly wind disappeared. We binned an almost full ~£50 bag of Eden.
I've seen Millies advising owners their food is not suitable if they don't think its best for the dog, I found Eden just wanted me to keep trying and trying even though my pup had had runny stools for months which cant have been good for him. I left a review for Eden on a website, not a bad one, just saying I seemed a good food but it didn't suit our dog and Eden were quite defensive and blaming me with their replies even though I'd tried every single thing they suggested.
We feed Millie's countryside mix and salmon & veg. Both are great for ddog. I've tried other Millies recipes and they were ok but the smelly wind returned so don't suit our dog, think it might be the trout or herring as they are a common factor in the Eden and the Millies recipes we tried.
Try Eden, it might suit your dog, but if it doesn't don't be sucked into keeping it going to months, its not worth it!
