  1. Chocolate

It is a well-known fact that chocolate is toxic to dogs, which is the biggest concern with chocolate-flavored supplements. 

Dogs cannot metabolize theobromine present in chocolates. Theobromine is a substance that gives pleasure to humans when eating chocolates. Theobromine is responsible for releasing happy chemicals in the human brain. It can prove to be fatal for your dog.

Caffeine can also prove to be toxic for canines. The majority of protein supplements available in the market contain caffeine. Caffeine is considered to stimulate energy and alertness in humans. 

Protein bars include caffeine in the form of tea or coffee extract.  Since dogs cannot process caffeine, it is not recommended.

Ingredients like brown rice syrup include an excessive amount of sugar. Sugar in excess isn’t healthy for your dogs, and its substitutes can prove to be even more toxic.

Xylitol is a chemical compound used in gums, chewable vitamins, and sweet tarts. It is a fact that xylitol is highly dangerous for dog consumption. Here is a list of symptoms usually observed 30 minutes after ingesting xylitol in any form:

  • Unsteadiness

You might not even notice signs of xylitol poisoning in your dog for a good 2-3 days. But you must keep xylitol-based food items at bay, or it can harm your dog’s liver. 

Even a bite-size of xylitol can be fatal for your little furry friend. It induces an abnormal amount of insulin in a dog’s body and reduces blood sugar levels.

NOTE: This condition is hypoglycemia which can cause coma, weakness, incoordination, and even death in dogs.
