better dog foods

I once had two dogs of almost the same age. One was a purebred, the other was from the same father dog, but from a mutt mother, so the puppies were half brother and sister.

They were raised in the same environment, I kept them in the same environment.

I noticed that the purebred had looser bowel movements. The veterinarian said that some dogs are just looser than others.

I switched one of the most expensive brands of dog food. The purebred's dropping became firm like the mixed breed dog's always had been.

But the mix breed dog became so constipated, that I had to go out and get him a sack of regular dog food.

I like to free feed my dogs, and let them go in and out the doggie door as they please, so feeding each dog a different food would be difficult.

I tried feeding them separate, and mixing the new food in with the old food for the mixed breed dog.

The end result was that the purebred dog did great on the expensive food, she was lively to the point of being annoying, she had plenty of energy, she was vibrant and active, she seemed much more alive.

But the cute mixed breed dog, seemed depressed, less focused, less active, less happy.

I tried going back to the regular dog food. The mix breed dog perked up, became energetic, and happy.

The purebred did better on a diet high in fats. The mixed breed dog did better on a diet of high in carbs.

They needed different foods.
