There are plenty that have been around a very long time.
If they are from here as a listed vendor, you will be fine. I will tell you that Christine's Chop Shop, and Texas Freeze Dried are good.
But when it comes to nutrition, we all can feed fresh and commercially prepared pelleted diets.
Treats loaded with fat, salt and pure toxicity is all WD is producing!
I haven't tried Christine's yet but I do hear good things from several people about that one. I make my own chop for him but it is nice to have a good backup in the cabinet when needed in a pinch.
He always has pellets available and he eats his fresh veggies/fruit very well.
We do shop AO also but I fully trust Danita and I buy from Sprout People as well! Other than that though it's all commercial foods we get from you
or the store if I need something in a pinch! It would be anyone new that comes along that would take time for me to trust enough to feed their food to Jenks unfortunately.
He counts on me to make sure his food is safe and like many on here I felt that I completely failed him with WD's. We just lucked out to be in the moving process during that time so he didn't get much of the food thankfully.
