Our dog tested hyperthyroid after eating Sundays beef recipe
We had four dogs that we believe were exposed to thyroid, but we only tested one dog but all 4 dogs had symptoms. During the vets entire career she had never seen a hyperthyroid dog. We just assumed the others would test the same as well. All dogs were taken off of Sundays and everybody is happy and healthy now. Within one month of stopping the food, her thyroid normalized. we were feeding the beef version. We had to spend thousands on their food and then a lot of vet bills because our dogs became aggressive with each other, which had never happened. I asked Sundays what they were going to do about it.. crickets. I finally decided I'm going to leave reviews about it because I am hoping other pet parents won't go through what we've been through. We don't even know if this will shorten the life of our dogs?! we don't know how long they were exposed. We love our babies. I wish they would tell us what happened.
