Vomiting & Diarrhea in Dogs and Cats

Vomiting and diarrhea are among the most common reasons pet owners contact our clinic. While an isolated, mild episode is sometimes not a cause for concern, ongoing or severe symptoms can signal a more serious underlying issue.

Possible Causes

  • Dietary indiscretion (eating something they shouldn’t have)
  • Sudden diet changes
  • Intestinal parasites
  • Food or environmental allergies
  • Infections
  • Toxin ingestion
  • Underlying conditions such as kidney or liver disease

When to Seek Care

Call us right away if your pet’s vomiting or diarrhea is severe, persistent, contains blood, or is accompanied by lethargy, loss of appetite, or signs of pain. Puppies, kittens, and senior pets can dehydrate quickly and may need care sooner than a healthy adult pet.

If you suspect your pet has eaten something toxic, see our seasonal alerts page for information on common household hazards, and call us at (254) 876-2552 right away.
