Mountain Graphic Underline

When your dog or cat has a chronic illness, unexplained symptoms, or a condition that isn't responding to routine treatment, veterinary internal medicine can provide the answers you've been looking for. At Timberline Veterinary Emergency & Specialty in Seattle, our internal medicine specialists evaluate and treat complex diseases affecting organ systems throughout the body—from the GI tract and kidneys to the endocrine system and beyond.

We also partner closely with primary care veterinarians by accepting referrals for advanced diagnostics, including ultrasound and endoscopy and CT, helping provide answers when cases require a deeper level of investigation.

If your veterinarian has recommended a specialist referral, or you're looking for a deeper level of care, contact us at (206) 828-6868.

From there, our board-certified specialist may recommend advanced diagnostics such as bloodwork, urinalysis, ultrasound, or endoscopy. Once results are in, your specialist will walk you through the findings, explain your pet's diagnosis in clear, understandable terms and outline a clear treatment plan.
