Canine IBD

Canine Chronic Enteropathy Study

We are currently enrolling dogs with chronic gastrointestinal inflammation into a study, the purpose of which is to develop a variety of non-invasive markers for dogs with gastrointestinal disease.


Recent research from your samples has made a difference and yielded interesting results.

New research would be limited without your continued support, especially identifying and enrolling patients in our studies. Thank you!

Patient eligibility

  • Dogs with chronic enteropathies that undergo a complete diagnostic workup that MUST include gastrointestinal biopsy
  • Dogs can have antibiotic responsive enteropathies, food responsive enteropathies, steroid-responsive enteropathies, or idiopathic IBD
  • Dogs of any age, breed, or sex are eligible to be enrolled

Required samples

Please note that testing is performed free of charge only if all required samples and paperwork (including questionnaires) are received for testing.

  • 1 pre-prandial fasted serum sample (at least 4 mL)
  • 1 pre-prandial EDTA blood sample (3 mL; as well as copies of recent CBCs, if available)
  • 3 fecal samples from consecutive bowel movements
  • 1 urine sample preferably collected by cystocentesis (at least 4 mL)
  • Gastrointestinal biopsies in buffered formalin

Client incentives

For eligible patients the study will pay for the following items on receipt of a full sample set and completed forms. We are unable to offer these tests free of charge for patients with incomplete paperwork (including questionnaires) or sample sets.

  • Serum concentrations of cobalamin, folate, TLI, PLI, gastrin, and C-reactive protein
  • Fecal Dysbiosis Index
  • Histopathology through the GI Lab (performed by pathologists with special expertise in the evaluation of gastrointestinal specimens)
  • All shipping costs related to sending samples to our lab

For patients with complete follow-up information, we offer the above tests up to 3 times for each patient (initial presentation and up to 2 rechecks).

Turnaround times

  • Same as regular sample submissions to the GI Lab
  • Usually next day for serum cobalamin, folate, TLI, PLI, and gastrin,  and fecal Dysbiosis Index
  • Up to 7-10 days for serum CRP, depending on the day of sample submission
  • 5-7 days for histopathology

If you are interested in enrolling one of your patients, please complete this form (enrollment form) and the study team will contact you. Please email for further details.

Please note: If you are the owner of the dog and not a veterinarian, please have your veterinarian contact the IBD Study team directly.
