At first, this may seem like a silly question because, look at it from a human perspective, what human actually likes raw yeast? There can’t be a lot of people that actually do. So, then it makes perfect sense why a dog wouldn’t like it. However, we are talking about dogs here and most dogs will eat just about anything in front of them. So, why is it that most dogs dislike yeast? Is it the taste? Or maybe it is the smell? Or could it possibly be something more medical related? Let’s dive right into the root cause of why dogs don’t yeast to find this answer
The Root of the Behavior
The biggest reasons that a dog doesn’t like yeast is because raw yeast is actually quite harmful to dogs. In fact, it can be so toxic to dogs that it can be life-threatening. If your dog did eat yeast (and there are dogs who will eat anything, including yeast) there are a couple of health concerns to worry about. The first concern is bloating. Yeast likes to rise in a and moist environment. When a dog ingests yeast it can rise and cause the dog’s stomach to expand and increase in size. The expanding of the stomach and the pressure can lead to bloat, a life-threatening condition in dogs. Symptoms of bloat include but are not limited to drooling, bloated abdomen, restlessness, heavy panting, shallow breathing, and pacing. If your dog develops bloat, there isn’t anything you can do for them except to get them to a vet immediately. Death from this can happen within a few short hours if not treated right away.
Also, there is a fermentation process that goes on when yeast rises, which produces ethanol. Ethanol is then absorbed into your dog’s bloodstream. Once this occurs, your dog is at high risk for alcohol poisoning. Symptoms of alcohol poisoning in a dog include vomiting (or attempting to vomit), staggering, weakness, panting, drooling, and hyperactivity. It can take a few hours before you see these symptoms as the yeast goes through the fermentation process. However, if you do see any of these signs after your dog ingested yeast, take him or her to the vet right away. Alcohol poisoning can cause other issues such as tremors, disorientation, hypothermia, respiratory issues, and hypoglycemia. So with that being said, most dogs probably don't like yeast because they are smart enough to know it could hurt them. However, this does not mean you can just leave yeast or raw dough lying around. Some dogs will eat just about anything they find so be sure to keep yeast out of your dog's reach.
