Recall Alert: Multiple Dog Treats Recalled Due to Potentially Elevated Levels of Beef Thyroid Hormone


A dog treat company is recalling multiple beef dog treat varieties because officials say they may contain elevated levels of a naturally-occurring beef thyroid hormone.

The company — Merrick Pet Care — issued the recall after the US Food and Drug Administration (FDA) shared one customer complaint. According to a recall notice, the customer’s dog reportedly experienced temporary health issues from eating Merrick Backcountry Great Plains Real Beef Jerky 4.5 ounce (full list of recalled products below). The dog fully recovered after he/she stopped eating the treat.

The Potential Symptoms

According to a recall notice, dogs who consume high levels of beef thyroid hormone may experience increased thirst and urination, weight loss, increased heart rate, and restlessness. Like in the case above, these symptoms may clear up once a dog stops eating the impacted treats.

If a dog consumes high levels for a long period of time, symptoms may increase in severity. Pet parents are urged to watch for vomiting, diarrhea, and rapid or labored breathing.
