so how much would i feed mine 8-9kg dogs

Hi
I've just looked on their website & it says:

DOG GRAMS PER DAY

5 - 10KG 103 - 217

They also deliver the food!

Inca, you could also join the breeders club with Arden Grange you get it quite a bit cheaper than the normal sell price.

We feed Arden Grange to all but two of our dogs, they love it, Denzel and Heidi eat the prestige, which is fairly high in protein, Holly eats the Adult and Tina has the light diet. They all look well on it and output is small and twice a day max Under the breeder scheme it is alot cheaper, but they do charge a delivery fee now £2.95 per delivery i think, but it still works out alot cheaper. http://www.ardengrange.com/
