So my choices are Orijen or Acana?
Both are nice foods.
which one do you think will be better??
Whichever your baby likes better . . . I would choose Orijen . . . Check your local pet store for samples. Instinct is also a great choice.
Does Acana have lower protein content then Orijen?
Yes it does
do your dogs actually eat this food well? (and not pick at it)
I haven't personally fed it, but it's going to depend upon each individual dog
Is it true that high protein dog food can fry the liver?
No.
High protein is a quality diet bc dogs are carnivors, after all. Some dogs have a rise in thirst, but I haven't noticed a difference.
will Polo likely gain weight cause of the high protein?
I believe it's the calories, not the protein Hope that helps! Good luck.
