I can't say definitively that these treats are the reason the dogs got sick, nor will I go to the time and expense of proving they are. But I do know, from now on, Barbie will only get treats that I make.
They're so easy to make, one batch gives you about 100. I'll scale it back to make more manageable quantity and post that recipe soon. They're gluten and corn free. Thankfully Barbie was feeling totally normal by Saturday evening. I was surprised how complicated a lot of the dog treat recipes I found online were, and that a lot of them had sugar. This recipe is very, very easy.
2 lb brown rice
6 slices bacon, chopped thin
15oz canned pumpkin
4 cups water
Dash iodized salt
Cook rice and bacon together, let cool
Combine cooked rice, pumpkin, eggs, and salt. Use small ice cream scoop and form like meatballs. Flatten spheres to discs. Cook at 275 until treats are dry and firm, about 1 hour
