Everyone has their favourite food. And all breeders think they do it best. Right? :-) :-)
There are lot on CD who would recommend AG. I have only bought it myself when on offer at Berriewoods or Titmus.
I know Barbara on here swears by it, and has reared lots of pups on it. Judging by the look of her dogs, I would say that you can't go far wrong. I don't know the breeder criteria, but would say it is definitely worth a phone call and a chat. I have seen good comments about their customer service.
You have nothing to lose by having a chat to them. :-)
And welcome to CD. Be warned though. It can become addictive. :-)
