GSD feeding

Hi all,

i have a 2 1/2 year old GSD he is roughly 34kgs, i am currently daily feeding him 395kg forthglade wet tray mixed with 440kg forthglade lightly baked. would anyone be able to advise if this is suitable and if i would be better off using a mixer instead of the lightly baked stuff. it is quite costly using the current combination.

thanks

Alan
