At what age should I change my pup from Nature Diet Puppy to the adult food?

I believe Naturediet recommend changing over to adult at 6 months.

I contacted NatureDiet about this for Dharma and they said 4 months for a large-giant breed, and 5-6 for a small-middling pup :)  They recommend that when they go onto the adult variety that you stick to the chicken and rice flavour. :)

Any idea why they do the other flavors then?

Yep - theyre for variety for adult dogs (and some are for specialised diets, eg the Lite one for senior or overweight dogs, etc). Obviously when your pup is fully grown, he'll be able to enjoy them too :D 

We've just changed our pup over to the Adult food and she's 4 1/2 months - they only recommend the puppy food up to approx 20 Kg and our pup is now 25.4 kg. We've put her on the original flavor to begin with as it had virtually the same ingredients as the puppy diet, just with less protein etc. We tried her on Chicken & Rice but she had a bit of diahorrea (sp) with it so we'll stick to original for a while - hth :)

would someone tell me what HTH means please :)

Either 'Hope This Helps' or 'Happy To Help'

Thankyou :)
