I have fed my dogs raw meaty bones for years. My vet bills have dropped to nothing (except any shots required by law).
It is not work, and it isn’t hard. Don’t pay attention to Billinghurst, Read Tom Lonsdale, he is much better. You can google his website - he is an outstanding vet from Australia.
Do not give doggie vitamins. Lonsdale explain why. No need to grind up veggie slop, either. And, either make your own pet treats, or buy from a trusted source, such as “SitStay” (online, very reliable, good shipper)
You will love the results, and be surprised how easy it is to toss out some raw meaty bones for your dogs dinner, and watch the joy in his/her face as they eat the way God planned.
I lived in New Zealand for almost 7 years. In 1999 when we got our first German Shepherd, dry dog food choices in the grocery store were pretty slim, but there was lots of fresh and frozen raw meat dog food choices. One town we lived near had a dedicated raw meat pet food shop we bought our food from for a while. We were told that when dry dog food started being used, the vets started seeing a lot of health problems they hadn’t seen before, and particularly more tumors.
