NEW! Healthy Dogs: Assessing Amino Acid Concentrations in Urine

Title: Amino Acid Concentrations in the Urine of Healthy Dogs

Purpose:  Amino acids are the building blocks of protein. We are trying to establish normal reference ranges for urinary amino acids in healthy dogs consuming dry, canned or commercial raw diets or home-prepared diets.


Participation Requirements:

  • Healthy dogs consuming dry, canned or commercial raw diets or home-prepared diets
  • Ineligible:
    • Beagles and Greyhounds
    • Dogs consuming foreign or domestic jerky treats in the past 12 months

Initial Evaluation for Participation: Before your pet begins the study, you will need to complete the Feeding History Form asking about your pet and what they currently eat at home to find out if he/she qualifies to be in the study.

Procedures: You will need to complete a questionnaire about your dog and what your dog is currently eating at home, collect a small amount of urine (a minimal amount of 15 ml or 1 TB) in a clean cup we provide, and submit 2-3 photographs of the label of the diet you are currently feeding your dog.


  • There is no cost to you to participate in this trial.
  • Results from this study may contribute to the development of a reference range for urinary amino acids in canine urine that will be used as part of a larger study to understand the severity and duration of urinary amino acid loss in dogs that develop acquired Fanconi syndrome.

Owner Responsibilities: If you wish to have your pet participate in this study, you will be responsible for completing the questionnaire to the best of your ability, collecting a small urine sample, taking 2-3 photographs of the label of your pet’s food and submitting those to the study investigators.

Cystine Bladder Stones: Investigating an Oral Nutraceutical Treatment

Title: The effects of an oral nutraceutical on the solubility of cystine in canine urine


  • Cystine bladder stones are common in both dogs and humans. This disease occurs due to a genetic predisposition, which occurs in many breeds of dogs. Therapeutic preventive strategies are limited.
  • Clinical signs can be mild or result in urethral obstruction in male dogs.
  • In a collaborative effort between the University of California San Francisco and The Buck Institute, the aim of this study is to evaluate the effects of an oral nutraceutical on cystine solubility in the urine.

Contact: Jodi L. Westropp DVM PhD DACVIM at, Sean Hulsebosch DVM DACVIM at, or make an appointment by calling (530) 752 – 1393.

Participation Requirements:

  • Dogs with a history of cystine stones
  • Healthy dogs with no history of cystine stones of similar breeds

Initial Evaluation for Participation: Known documented history of cystine stones


  • A physical exam, abdominal ultrasound, blood and urine testing will be performed.
  • No follow-up visits will be required; however, urine samples will need to be collected at home after receiving the oral nutraceutical for one week.


  • Free screening and diagnostic testing for your pet, including abdominal ultrasound, bloodwork and urinalyses
  • We hope that the data acquired in this study will allow us to advance the prevention of cystine bladder stones in both pets and people.

Owner Responsibilities:

  • Keeping the scheduled appointment
  • Administering the oral nutraceutical for 7 days
  • Three, at-home, urine collections while administering the medication to your dog
