Canine atopic dermatitis (CAD) is a common allergic skin disease of dogs with a strong genetic basis. Evidence from human studies suggests that several variants of AD exist with different mechanisms and responses to treatment. Current diagnosis of CAD requires time-consuming procedures that involve a considerable cost to the owner. Therefore, new approaches to identify molecular markers that can help with better diagnosis and management of the disease are warranted. In this study, we are using our tailored methodology for lipid biomarker discovery in CAD.
The preparations for the CBD epilepsy study were started in December 2018, including hiring a fulltime research assistant and part-time work/study student, creating all of the study documents necessary for the trial, and creating a newsletter/announcement for Colorado veterinarians. We began enrolling patients for the study at the end of January 2018. We anticipated enrolling 20 patients per year; therefore, we are on track with 54 patients in 2 1/2 years.
Initial studies on cytotoxicity by the research team show that CBD has cytotoxic activity on a variety of canine cancer cell lines at modest concentrations in the laboratory. These effects cause apoptosis, or programmed cell death, within a very short time frame, suggesting a discrete mechanism.

Dilated cardiomyopathy (DCM) is the second most common cause of heart disease in dogs, and medical management of the secondary signs is the only therapeutic option. The outcome for affected dogs depends on the stage of disease and the breed. Once diagnosed, dogs typically exhibit rapid and uniform progression to congestive heart failure (CHF), with most living less than 6 months.
The study titled “Investigation into Subclinical Diet-Associated Dilated Cardiomyopathy in Four Dog Breeds” is progressing on schedule. Enrollment for the first part of the study is at approximately 85%. We are aiming to finish enrollment by late spring/early summer, after which time we will concentrate on data collation and statistical analysis for the first part of the study.
This AKC-CHF sponsored award supported the successful development of a comprehensive canine tumor sequencing panel (“canine oncopanel”) using cutting-edge, next-generation sequencing technology.
Hypoadrenocorticism or Addison’s disease (AD) consists of a life-threatening clinical condition that afflicts multiple purebred and mixed breed dogs. The condition results from autoimmune destruction of the adrenal glands leading to life-long cortisol deficiency.

Hemangiosarcoma (HSA) accounts for the majority of canine malignant splenic tumors and occurs in many large dog breeds, including mixed breeds. A less common site of HSA localization is the heart (cardiac HSA). Risk factors for both cardiac and splenic HSA remain unclear, confounding development of preventative strategies. The investigators recently reported a high prevalence of species of the bacterial genus Bartonella in dogs with HSA from North Carolina, suggesting a potential role in the initiation and/or progression of this cancer.
The goal of this project is to identify autoantibodies that are present in the blood of dogs who are newly diagnosed with Addison’s disease in three breeds: Standard Poodles, Portuguese Water Dogs, and English Cocker Spaniels. To accomplish these goals, we have been focusing on (1) collecting blood samples from dogs across all three target breeds, and (2) employing methods that allow us to detect these autoantibodies.
Cruciate ligament rupture (CR) is a common disabling, degenerative condition of the knee. It places a large financial burden on the American public. Inflammation of the stifle and fraying of cruciate ligament fibers, particularly in the cranial cruciate ligament, eventually leads to ligament rupture with associated stifle instability in affected dogs. CR is a moderately heritable, complex disease with genetic and environmental risk.
