Hill’s ZD Dog Food Side Effects

Hill’s ZD Dog Food Side Effects – Everything You Need To Know

Hill’s Pet Nutrition is a reputed pet food company in the United States that produces canned or packed food for cats and dogs. Many veterinarians suggest Hill’s diet food for pets because they provide the exact nutritious and vital ingredients needed for them. Hill’s pet nutrition has been giving its best quality food product for pets for many years.

But recently, the U.S Food and Drug Administration (FDA) has investigated the presence of potentially toxic vitamin D levels in some of their food because of some complaints of the consumers who have faced some misery. And after the investigation, Hill’s company recalled some of their canned food. Among them, Hill’s Z/D canned food was also listed there.

Hill’s nutritionists and veterinarians designed z/d food to support your dog’s skin and food allergies. These foods helped you to prevent food allergies of dogs. But it has proven now that these foods have excessive vitamin D, which can be harmful to dogs. These are some side effects that can show up:

  1. Vomit
  2. Diarrhea
  3. Little Appetite
  4. Drooling
  5. Bradycardia/ high blood rate
  6. Allergic Reactions
  7. Weight loss
  8. Renal failure
  9. Kidney failure
  10. Joint issues
  11. Death


Excess calcium in the blood is linked to several of the negative effects of too much vitamin D. Nausea and vomiting are some of the major side effects of vitamin D toxicity. Though optimum vitamin D enriched food is essential for preventing the skin allergy of pet dogs, a little extra dose of vitamin D causes the indigestion of the dog. This excess of vitamin D is found to be very toxic for dogs. Vitamin D poisoning can be caused by as low as 0.1 mg/kg of vitamin D.


Besides vomiting, nausea, and indigestion, diarrhea is also another vital side effect of Hill’s Z/D food. Usually, change in diet, travel, boarding, or other changes in environment and attack of parasites causes diarrhea for dogs. Excess levels of vitamin D in dog food also cause diarrhea. Vomiting and nausea can also happen with it.

Little Appetite

Hill’s Z/D dog food contains excessive vitamin D. As this toxicity of vitamin D causes vomiting and diarrhea, it reduces the desire of eating for the pup. This is called little appetite.

Although a loss of appetite in dogs does not always signal serious illness, it is also crucial, as this can be the prior symptoms of other dog diseases. To avoid further complexity, you should seek veterinary help right away since it might be a symptom of serious sicknesses, such as cancer, different systemic infections, discomfort, liver issues, or renal failure.


Drool can be caused by anything that inhibits your dog from swallowing regularly since saliva will build up until it drops from his mouth. Consuming vitamin D in toxic levels can result in the excessive drooling of your mutt.

Bradycardia Or High Blood Rate

Due to the toxicity of vitamin D, the blood rate of your dog may change. This can drive the blood circulation either very fast or too slow. Vitamin D deficiency can cause a heart attack or heart failure, but excessive amounts of vitamin d in ZD food also result in serious heart problems for dogs.

Allergic Reactions

If the dog is allergic to a particular ingredient of the food, it will cause an allergic reaction leading to diarrhea and vomiting. So, these are a few of the side effects of Hills Zd dog food. Before giving this food to your puppies, make sure that they don’t have any health issues. After all, if you feed them a proper diet and if they have some health issues, then it will cause even more damage.

Weight Loss

Weight loss of your little furry friend can be caused by many reasons. Vomiting, nausea, and other diseases like kidney or heart problems can result in weight loss. If your dog is refusing to eat, losing weight, or has any other digestive or feeding difficulties, take precautions and have your pooch examined by a veterinarian.

Renal Failure

Vitamin D toxicity can develop in dogs with a pet diet containing too much vitamin D. It can result in a pup drinking and urinating more. Thirst and water consumption are raised to protect the dog from getting dehydrated due to increased fluid loss in the urine.

As a result, increased water consumption and urination are some of the first clinical indications of kidney failure, referred to as compensated renal failure.

Kidney Failure

Kidneys in good shape control hydration, maintain a proper electrolyte balance, release hormones required for red blood cell production, and eliminate pollutants. Vitamin D is a fat-soluble vitamin that helps the body absorb calcium and other nutrients.

When a dog gets too much vitamin D, the excess is not exerted rapidly from urine. The stored excess vitamin D in the body damages the tissues. This causes the failure of the kidney and even also the liver of the dog.

Joint Issues

Joint issues would happen to your pets for the deficiency of calcium. Excessive vitamin D in food absorbs the calcium of the dog’s body. Also, dogs with toxicities from vitamin D may have kidney diseases. Hyperparathyroidism may be caused due to kidney diseases. It is a disease of sluggishness and severe weakness of the dog.


Toxicosis from vitamin D is a serious life-threatening disease that can cause death to your pet dog. If your puppy is consuming Hill’s ZD canned food for a long time, it may suffer from many diseases and, after severances that can even lead to death.

Kidney failure and hyperkalemia can happen, and this can cause premature death. If left untreated, dogs will die from a vitamin D overdose within several days.
