Vomiting & Diarrhea in Pets That Won't Stop: Causes & What to Do

Vomiting and diarrhea are common issues in both dogs and cats, and they can be alarming for pet owners. Today, our Lebanon vets help you understand the causes, severity levels, and when to seek emergency care for your dog or cat.

Why is my cat or dog vomiting or experiencing diarrhea?

Vomiting and diarrhea are common symptoms of gastrointestinal upset, inflammation or irritation of the stomach or intestines.

Although seeing your pet experience these symptoms can be alarming, vomiting is your pet's way of getting rid of spoiled food or indigestible material in its stomach to prevent it from causing further harm.

On the other hand, diarrhea occurs when the indigestible material has passed through your pet's digestive system and is expelled.

However, pet owners may not always know if their furry friend is experiencing these symptoms due to having indigestible material in their system or if something more sinister is at play.

What is causing my cat's or dog's vomiting and diarrhea? 

A variety of potential causes may contribute to vomiting and diarrhea in your dog or cat, including:

  • A reaction to spoiled food
  • Bacterial infections 
  • Colitis
  • Change in diet or treats
  • Inflammatory bowel disease
  • Ingesting poisons or toxins 
  • Ingesting foreign objects such as fabric or toys
  • Medications, such as antibiotics
  • Anxiety or stress 
  • Parasites
  • Viruses
  • Organ problems
  • Kidney or liver disease
  • Cancer 
  • Pancreatitis

If your pet continues to vomit or have diarrhea and you're unsure why, contact your vet for an appointment. Your vet can assess your pet's symptoms and accurately diagnose the problem. 

What should I do if my cat or dog won't stop vomiting or having diarrhea? 

If your pet has a single episode of vomiting or diarrhea but is otherwise acting normally, this is usually not a cause for concern. However, monitoring your pet's bowel movements is important to see if the issue resolves. 

If two or more episodes of vomiting or diarrhea occur quickly, this may indicate an underlying problem, so it's best to seek advice from your vet. 

Some pets may strain to pass stool and only produce small amounts of watery diarrhea. This could be a symptom of a severe blockage caused by ingesting a foreign object, such as a toy. In these situations, immediate veterinary attention is needed, so it's important to contact your vet or go to your nearest animal hospital that offers emergency care. 

Recurring vomiting or diarrhea over a short period is concerning, especially for older pets, young pets, or those with a weaker immune system. Some infections may be severe or even life-threatening, so it's critical to contact your vet promptly if your cat or dog is experiencing repeated bouts of diarrhea and vomiting. 

If additional symptoms appear, in addition to vomiting and diarrhea, it's important to seek veterinary attention immediately. Contact your vet right away to schedule an appointment if your pet has any of these symptoms:

  • Weakness 
  • Blood in their stool 
  • Unusual drooling 
  • Lack of appetite 
  • Signs of dehydration (sunken, dry-looking eyes, dry, sticky gums, or dry nose)

If your cat or dog is displaying symptoms that are causing you concern, contact your veterinarian as soon as possible. Your vet can tell you whether your pet's symptoms indicate a need for examination and treatment. 

How are vomiting and diarrhea in cats and dogs treated?

Treatment for vomiting and diarrhea in cats and dogs typically involves withholding food for 12-24 hours to allow the gastrointestinal tract to rest. It is important to ensure they have access to fresh water to prevent dehydration. Once the fasting period is over, a bland diet such as boiled chicken and rice can be gradually reintroduced in small amounts to help soothe the stomach.

In cases where vomiting and diarrhea persist or are accompanied by other symptoms, such as those listed above, it is crucial to seek veterinary care. Your veterinarian may recommend medications such as anti-nausea drugs, probiotics, or antibiotics depending on the underlying cause of the gastrointestinal upset. It is important to follow your veterinarian's recommendations closely and monitor your pet's condition closely during recovery.

How can I prevent vomiting and diarrhea in my pet?

To prevent your pet from vomiting or getting diarrhea, it is important to ensure they have a balanced diet. Avoid feeding them table scraps or foods that are high in fat, as this can upset their stomach and lead to digestive issues. Additionally, make sure your pet has access to fresh water at all times to stay hydrated and aid in digestion.

Regular exercise is also crucial in maintaining your pet's overall health and preventing gastrointestinal issues. Physical activity helps regulate their metabolism and keeps their digestive system functioning properly. If you notice any changes in your pet's eating habits or behavior, consult with a veterinarian to address any potential underlying health concerns that may be contributing to vomiting or diarrhea.
