Dog health

Today we were watching tv. We saw how a dog had bone problems and because of that they were going to cut the nerves, so that it wouldn't have pain anymore, sounds quite nice doesn't it.
But then I was thinking, since our dog doesn't eat kibble (processed foods!) anymore she has become much healthier, is like a puppy again, is totally fit, has more energy than the average 3yo dog. Her bone structure became much better etc.
So why isn't there a vet recommending a change of diet.

Next piece was about a dog which had lots of teeth and gum problems. They were polishing and cleaning and burning way fleshy area's.
Funny, since our dog is on the Raw Meaty Bones or the BARF or the evolutionary correct diet, which ever you want to call it, she doesn't have any gum or teeth problems anymore, all is clean and strong.
Hmmmm.... why is there no vet recommending that then.
Hardly any vet I've found out. The vet here actually came with the comment that our dog was overweight, yeah a bit, in winter, always. Doesn't bother me. It goes away in spring, she obviously needs a bit of keeping warm layer, who cares.
So the vet comes up with the luminous idea that we have to change her diet as she will be getting way way way way too much protein when she is fed meat daily..... :???: meat daily - we said raw meaty bones daily, which is pretty different. Tried to explain this to the guy and the vet woman working with him. Didn't hit base. So we just nodded and let it slide, not worth the effort.

And then with all this on tv and this vet telling us to change to a 4th best diet I got thinking bad thoughts. What if those people are all doing this just so they keep filling their pockets. Maybe a lot of medicos don't even know it anymore, but I am quite sure that with all the diet recommendations for animals and humans which are - to my opinion - all wrong, there are quite some people nicely filling their pockets who would have to look for another job otherwise.
