Just want to give my experience with 4Health. I fed it for years to a few dogs. Then my current dog had to go to an emergency clinic a couple hours away to drain fluid from his chest cavity and spend some time in an oxygen tank. They were saying possible cancer, didn’t look good, etc. but could not give a definite for why this had happened. I knew something was wrong because he was struggling to breathe even at rest. They drained a lot of fluid and said it would take some time for him to recover and there was no promise the fluid wouldn’t come right back.
Long story short, I did what we all do and scoured the internet trying to figure out what had caused this and if there was anything I could do to prevent it reoccurring. What I found out was that some dog foods that use legumes like peas and lentils have been suspected of being linked to dogs that developed pleurisy.
I read the label of the 4Health Sensitive Skin and Coat (or whatever it’s called…used to be a white bag with a husky on the front) and found that peas were a main ingredient. There’s more to it than simply being peas = bad, it’s something about how the ingredients in “grain free” dog foods don’t contain something that limits something else or…something. LOL. It’s been a while sense I went down the rabbit hole.
Bottom line. I switched from the food, went through a few (Orijen was one, can’t remember others), and even did the Ollie human grade food and then just cooking for him for awhile (he wasn’t eating well at all for a few weeks after his hospital stay). Finally landed on Purina Pro Plan Sensitive Skin and Stomach. He’s been right as rain since. Skin and coat are the best ever, and no hint of the pleurisy returned.
A little over a year prior to this experience, my older (but not old) dog got extremely sick and the vet was stumped. Never could figure out what was wrong with him. I lost him to the mystery sickness.
I’m not saying it was the 4Health, but I’m never feeding it again. I’m sure plenty of dogs live long, healthy, happy lives on it.
