Great to read youatopped giving kibble. It is such nasty "food". I wondered long time ago why we give that too animals because it does not grow in nature and it is filled with stuff that is just junk.
I see you cook them,ever thought about giving it raw?
I gave my dog the last years of her life only raw meat and she loved it.
I then came across BARF.
