Patients are required to return for a 24 hour post-antivenom administration recheck and free bloodwork (CBC, chemistry, coagulation panel). Owners must commit to the 24 hour recheck as well as use of their pet’s photos and/or videos for research and publication purposes.

Internal Medicine

Canine Bile Acid Diarrhea and Microbial Dysbiosis Study

*NEW* We are enrolling dogs with signs of inflammatory bowel disease, with or without histopathologic evidence, that are on current standard therapies (prednisone, diet) but continue to have diarrhea. A GI panel and fecal analysis for bile acid concentration and enteropathogens, along with a dysbiosis index will be performed through the GI Lab at Texas A&M. Dogs with a non-GI disease to explain their sign will be excluded. Patients will be randomly assigned into a placebo or cholestyramine group. Owners will be asked to grade their dog’s feces daily. Dogs will be re-evaluated at 3, 6, and 16 weeks post induction of therapies. At these rechecks, a fecal sample will be collected and submitted for a fecal bile acid analysis and microbial evaluation. All study related expenses will be funded. Cost to initial diagnosis of a chronic enteropathy will be covered by clients.

Clinical Trial for Diabetic Dogs

VSH is participating in an exciting new clinical trial using a novel stem cell therapy to resolve diabetes mellitus in dogs! Dogs must weigh 5 to 12 kg, and be free of significant other systemic illnesses, on insulin (preferably Vetsulin), and at least partially controlled. Owners must be willing to perform glucose curves at home (with training), and to reliably bring the dog in for follow-up visits over 3 years. All study-associated costs are covered for the study duration (labs, procedures, insulin, glucometer, exams, etc.), including the initial screening visit, so we encourage any potential candidates to come in for formal screening with Drs. Loy Son, Gil, Dong, or Fischer.
