I could survive on processed museli bar type foods, but i wouldnt be at my optimum and 'healthy'...
Same for dogs!
I know i would be healthy if i stopeed process foods and ate more raw fresh foods, so i do that for my dogs
Regardless of whats actually in the processed food you just have to think logically to realise what is best for your dog to eat and dry little biscuits isnt it! Lol
