yep, dogs know which grasses are good for them. I have “been owned” by several different breeds, and I noticed that most of them all loved “grass hamburgers”
You know, the clumps left over after mowing? And they seemed to prefer the ones several day old, probably beginning to ferment. Must have been some tasty nutrients in them, just as in rabbit poop, etc.
Nothing that modern dog food companies understand, when they cook it all to oblivion. But, why should we worry, for we are now steadily heading that way, what with “ensure” and all.
I always fed my dogs eagle pack, and even my black lab was lean and mean. Their coats were nice and they had energy to burn. I think that was a good food.
I wouldn’t argue the raw stuff though either.
It’s been a year since someone stole my two beautiful dogs. Wife had left and they were my only company I had on my acreage, then I got home one night, and they were gone.
