I bet if you ask 20 people how to feed - you'll get twenty different answers
For me, and for many reasons, I feed a homemade raw recipe with all human grade ingredients and supplements. This recipe was created by my mother who has extensive knowledge in dog nutrition. The recipe has been reviewed and approved by my vet - who also has extensive knowledge on dog nutrition.
I serve it with confidence. It has lean hamburger, ground turkey, cottage cheese, rice, eggs, vegetables and supplements. Feel free to pm me if you're interested.
