This has been a topic of discussion on the Border Collie groups off and on. It's a fact that
still overseas, these hard working dogs are fed farm scraps, table scraps, chicken mash, and whatever else they can pick up. It's also a fact that some go blind from retinal scarring caused by insufficient nutrition. However, other than that, the vast majority live long, healthy, very active lives.
I think the answer is simple - survival of the fittest. Our pets today don't undergo the hard knock lives that their predecessors did, and each generation gets a little "softer." Breeders don't cull dogs just because they have allergies, or require a little bit better food to keep condition, or have to have supplements to keep their skin and coat in top shape.
The other thing is increased pollution and contamination of the food supply has a lot to do with it, I'm sure. The soil just isn't as fertile as it was, and the demands of the public for cheap food have made it impossible for farmers to avoid genetic engineering of plants and hormonal and antibiotic augmentation of livestock.
With regard to OFAs, the biggest reason our food is deficient in these is that we are growing our livestock too quickly. I tell my dog food customers to select the oldest animals for their dogs, as they are the highest in OFAs and GAGs (joint lubricants).
