For over a year I've fed both mine girls on Arden Grange and changed to Autarky recently as it was on sale in our local farm shop.  They have had no problems with it and are nearly at the end of their bag.  The reason to this post, is that my youngest bitch is (hopefully) nearly 6 wks pregnant and I don't know whether to go back to AG or buy more Autarky.  Also, what would be best for the pups?  

thanks for any advice
