Does anyone else use this dry dog food for their fur babies? We have used this for years with no problems but we recently opened a new bag and it made my schnoodle very sick

We all had a stomach bug last week so we thought Gatsby got a touch of it because he started vomiting yellow bile during the night. Then it got worse and he broke out in these huge bumps under his skin that felt like hives. They were around his eyes too. So we stopped the food and are giving him chicken and rice and benedryl. He is much better today but I feel so bad that we just kept giving him the food...
Anyone else experiencing this? If not, heads up if your dog eats this. I've read a lot of complaints from Oct and Nov but no recalls that I can see yet. We have a call in to the vet too.

Try a bland diet (boiled chicken and rice) for 2-3 days and then try the food again. If it happens again call your vet and let them know as well as call the company. If it is the food it could be just that bag.

I have no experience with dog allergies but I do know that food can and does cause hives in humans with food allergies. Chemicals in foods can also cause hives in humans (without an allergy).
Are dogs different?
I'm genuinely curious as I truly know little to nothing about dog allergies (or dog health).

@aggiebug this was definitely the food. The more we gave him, the worse it got. But our dog is very sensitive (almost died from vaccination reactions once) so maybe that was another way it manifested in him besides the vomiting. We'll see what the vet says.
I think we will call the company too. Thanks everyone.

Dogs are different. The don't respond to food allergies/sensitivities with facial swelling, hives, etc like people do. Many allergic reactions can cause vomiting and diarrhea secondary to histamine release. Allergic reactions seen in dogs are typically secondary to vaccines, insect bites, etc.

I learned something new today! Always a good day when I learn something new! :-)
I hope your fur baby feels better soon!
