Can anyone help me with the cost of Eagle Pack as compared to the ZD diet. Iam pretty sure I could feed my allergic boxer the fish based diet as I am looking for an alternative to the ZD which is very expensive. (I think its about $75 for about 8 kilos). My dog cannot have chicken or lamb so at the moment we give him kangaroo and rice and other fresh food supplemented with the ZD. I would appreciate any help. I don't think anyone local stocks the Eagle brand as we are in the country.
