Digital X-Rays for Clear Diagnostic Insight
Digital radiography is one of the most valuable diagnostic tools in veterinary medicine. Our hospital in Rye Brook, we use modern digital X-ray equipment that produces high-resolution images almost instantly, allowing our veterinarians to evaluate your pet's internal structures with precision and clarity.
Digital X-rays help us assess bones and joints for fractures, arthritis, and developmental conditions such as hip dysplasia, as well as the chest for signs of pneumonia, heart enlargement, or fluid accumulation. Abdominal organs can be evaluated for size, positioning, and foreign body ingestion, while spinal imaging helps identify disc disease or abnormalities contributing to pain or neurological symptoms.
Compared to traditional film X-ray, digital radiography produces significantly less radiation, delivers results faster, and allows images to be enhanced, shared, and stored electronically. If a specialist referral is needed, images can be transmitted immediately for a second opinion.
Non-Invasive Ultrasound Imaging for Pets
Ultrasound imaging is a non-invasive diagnostic tool that uses sound waves to produce real-time images of your pet's internal organs and soft tissues. Unlike X-rays, which are best suited for evaluating bones and dense structures, ultrasound excels at providing detailed views of soft tissue, organ texture, fluid presence, and movement.
At Rye Harrison Veterinary Hospital, ultrasound is used to examine abdominal organs such as the liver, kidneys, spleen, bladder, and gastrointestinal tract, evaluate the heart's structure and function, detect abnormal fluid accumulation, and identify masses or cysts within organs that may not be visible on X-ray. It can also guide needle placement during minimally invasive biopsies or fluid aspirations and monitor pregnancy and fetal development.
Ultrasound is painless and typically requires no sedation, making it a low-stress option for pets of all ages. It is often used alongside digital X-rays to give our veterinarians the most complete diagnostic picture possible.

Allergy Testing
Allergies are among the most commonly misunderstood and underdiagnosed conditions in pets. Chronic scratching, recurring ear infections, hair loss, skin redness, and gastrointestinal upset can all be signs that your pet is reacting to something in their environment or diet. At our Rye Brook animal hospital, we offer allergy testing to identify the root cause of your pet's symptoms rather than simply managing them with ongoing medication.
Common signs that may indicate allergies in pets include:
- Persistent itching, licking, or chewing of paws, legs, or belly
- Recurring ear infections or head shaking
- Red, inflamed, or flaky skin and hair loss or hot spots
- Watery eyes or nasal discharge
- Chronic vomiting or loose stools
Dermatology
Dermatology refers to the diagnosis and treatment of conditions affecting the skin, hair, feet, nails, and eyes. When a pet experiences skin irritation, it is generally referred to as dermatitis until a specific diagnosis is reached. Dermatitis can be deeply uncomfortable and even painful for pets, often affecting their behavior and overall happiness on a day-to-day basis.
Managing dermatitis frequently requires a long-term commitment to veterinary care, sometimes spanning months or even years. Having a veterinarian you trust and feel comfortable communicating with makes a significant difference in finding lasting relief for your pet. At Rye Harrison Veterinary Hospital, our Rye Brook team takes the time to work through each case carefully and keep you informed throughout the process.
The following symptoms may be signs that your pet is dealing with a form of dermatitis:
- Regularly licking the skin, particularly the paws
- Itching or scratching of the skin
- Red or watery eyes
- Irritability or unusual aggression
- Sensitivity toward a specific area of the body when touched
- Red or inflamed skin
- Hair loss
Allergy Testing
Allergies are one of the most common dermatological problems affecting pets. Just like humans, pets can be allergic to a wide range of triggers including pollen, dander, mold, insect bites, and foods. Identifying the specific allergen is the first step toward effective, targeted treatment rather than ongoing symptom management.
At Rye Harrison Veterinary Hospital, we offer allergy testing to determine whether your pet has allergies and what they are reacting to. Once identified, there are a variety of treatment approaches available, ranging from allergy shots and daily oral medications to topical treatments. Your veterinarian will work with you to choose the most appropriate option based on the severity of the reaction, whether the allergen can be avoided, and the lifestyle and routine of both you and your pet.
