When your dog turns away from their food bowl, or your cat is vomiting for the third time in a week, the worry sets in fast. Gastrointestinal issues are among the most common health concerns pet owners face, and when left untreated, they can quickly escalate from discomfort to serious illness. Understanding what your pet is experiencing and knowing where to turn for expert care can make all the difference in their recovery.

At Montclair Veterinary Associates, Dr. Cory Waxman and his team have been diagnosing and treating stomach and GI issues in pets across Montclair and Northern NJ since 2011. With a background from the University of Pennsylvania School of Veterinary Medicine and years of hands-on experience in a wide array of veterinary services, Dr. Waxman brings a thorough, compassionate approach to every gastrointestinal concern that walks through the door.

Common GI Issues We See in Pets

Gastrointestinal conditions in pets range from mild and transient to chronic and complex. Knowing what to watch for is the first step in getting your pet the care they need.

Vomiting and Diarrhea

Occasional vomiting or loose stool can result from something as simple as a dietary change or eating something outside, but frequent episodes often point to something more serious. Conditions like gastroenteritis, intestinal parasites, dietary intolerance, or inflammatory bowel disease (IBD) can all cause these symptoms. According to the American Veterinary Medical Association, GI diseases consistently rank among the top reasons pet owners seek veterinary care each year.

Decreased Appetite and Lethargy

When a pet stops eating or becomes unusually lethargic alongside GI symptoms, it can signal a more serious underlying condition such as pancreatitis, a foreign body obstruction, or an infection affecting the digestive tract. These cases typically require prompt diagnostics to identify the root cause and develop an appropriate treatment plan.

Chronic Conditions

Some pets experience recurring digestive trouble for weeks or months. Chronic GI issues like IBD, food allergies, or motility disorders require a different approach than acute illness. At Montclair Veterinary Associates, Dr. Waxman takes the time to explore these ongoing concerns thoroughly rather than simply managing symptoms. Our pet management services for acute and chronic illnesses are built specifically for pets dealing with long-term health challenges.

When to Bring Your Pet In for GI Symptoms

One of the most common questions Dr. Waxman hears from Montclair pet owners is: How do I know when it’s time to come in? While a single episode of vomiting or soft stool can sometimes resolve on its own, there are clear warning signs that indicate your pet needs to be seen by a veterinarian promptly.

The following symptoms may warrant a visit to Montclair Veterinary Associates:

  • Vomiting or diarrhea that persists for more than 24 to 48 hours
  • Blood in the stool or vomit
  • Signs of abdominal pain, such as hunching, whining, or reluctance to move
  • Significant loss of appetite lasting more than a day
  • Noticeable bloating or a distended abdomen
  • Extreme lethargy combined with any digestive symptom


These signs can point to conditions that require immediate diagnostic attention, from intestinal parasites and infections to more serious concerns like pancreatitis or a foreign body obstruction. Our team can run bloodwork and imaging on-site to get to the bottom of what your pet is experiencing without unnecessary delays. The sooner a GI issue is properly identified, the better the outcome tends to be, which is why waiting is rarely the right call when your pet is clearly uncomfortable.

How We Diagnose GI Problems at Montclair Veterinary Associates

Accurate diagnosis is the foundation of effective treatment. Not all stomach issues look the same from the outside, and getting to the real cause requires more than a physical exam alone.

In-House Diagnostics

Our practice is equipped with an in-house laboratory and X-ray capabilities, which means we can run bloodwork, fecal tests, and imaging right here at the clinic rather than sending samples out and waiting days for results. This allows Dr. Waxman to act quickly when time-sensitive decisions must be made and helps rule out conditions such as organ dysfunction, intestinal blockages, or infections more efficiently.

Ultrasonography

For GI conditions that require a closer look at abdominal structures, our team can coordinate ultrasonography consultations to evaluate the stomach, intestines, liver, and pancreas in real time. This non-invasive imaging tool is particularly useful in diagnosing IBD, identifying masses, and assessing organ health when X-rays alone don’t provide a complete picture.

What Treatment May Look Like

GI treatment at Montclair Veterinary Associates is never one-size-fits-all. Depending on the diagnostic findings, treatment may include dietary modifications, such as transitioning to a prescription diet, which our team can source directly through our in-house prescription food options. For infections or inflammation, medications may be prescribed. In cases of obstruction or soft tissue concerns, surgical consultation may be recommended.

Our approach is guided by the belief that pets deserve the same thoughtful, individualized care that any patient would, and Dr. Waxman’s extensive clinical background ensures that every case is treated with that level of attention. Routine wellness exams also play an important role in catching GI issues early, before they become harder to manage.
