Kirstie M… I guess, the best reason I can think of to feed sardines is because they are so nutrient dense. High quality protein. Bones and “guts” intact – also one comment endorses feeding raw sardines, but I have no idea where to get them on a consistent basis. Freeze dried might be a good option:http://www.mycanadianpets.ca/gpage3.html.
I’m getting an Irish Setter puppy in a few weeks and I will be supplementing her kibble diet with some sardines, as well as some lightly steamed vegetables (http://dogaware.com/articles/dwveggies.html) and a little fruit. I also am thinking I will add dehydrated Green Tripe: http://ivcjournal.com/raw-green-tripe/.
I think you should relax. Even dogs are only fed med-high quality kibble seem to do just fine. I have a 13 year old Aussie bitch who’s eaten mostly Purina One dog food all of her life. She has been virtually problem free health wise, and still acts like a much younger dog. I’ve moved her to a grain free of late, and she likes it better and continues to do very well.
Hope this is of use to you.
