Recurrent episodes of oral mite anaphylaxis in a dog.

OBJECTIVE: To describe the clinical presentation and response to management of a dog with presumed oral mite anaphylaxis. CASE SUMMARY: A 2-year-old male intact Golden Retriever was evaluated for a history of recurrent anaphylactic episodes. Over a period of 19 months, the dog had a total of 8 anaphylactic episodes that occurred in 2 different residences within the same state. The episodes most commonly resulted in vomiting and labored breathing, but the dog developed ascites, hypotension, and gall bladder wall edema during the most severe episodes. Serological testing demonstrated high immunoglobulin E levels to storage mites (SMs), specifically Tyrophagus SM. The dog's kibble was transitioned to being stored in small quantities in airtight containers in the freezer. At the time of publication, the dog has not had an anaphylactic reaction since making this change 1 year ago. NEW OR UNIQUE INFORMATION PROVIDED: Based on a literature search and to the best of the authors' knowledge, this is the first time that SMs have been associated with severe recurrent anaphylaxis in a dog.

Use of the Health Belief Model to identify factors associated with owner adherence to elimination diet trial recommendations in dogs.

OBJECTIVE: To use the Health Belief Model to identify factors associated with owner adherence to elimination diet trial (EDT) recommendations by veterinarians for dogs with suspected cutaneous adverse food reactions (CAFRs). SAMPLE: 192 owners of dogs prescribed an EDT between April 1, 2012, and April 1, 2017. PROCEDURES: Owners of dogs prescribed an EDT to diagnose CAFRs were identified through review of medical records from a single veterinary dermatology specialty practice. Identified owners were invited to participate in an anonymous online survey that was developed on the basis of the Health Belief Model. Multivariable logistic regression was used to evaluate associations between potential predictor variables and 100% adherence to EDT recommendations. RESULTS: 665 owners were invited to participate, and 192 (28.9%) completed the survey. Of the 192 respondents, 77 (40.1%) reported 100% adherence to EDT recommendations, and 115 (59.9%) reported < 100% adherence. Results indicated that the odds of owners reporting 100% adherence to EDT recommendations were significantly decreased by owner perception of barriers (adjusted OR [ORa] = 0.86) and were significantly increased by owner knowledge regarding diets and CAFRs in dogs (ORa = 1.30) and by self-efficacy or confidence in performing an EDT as directed (ORa = 1.18). CONCLUSIONS AND CLINICAL RELEVANCE: Findings indicated that most prescribed EDTs were not followed strictly. Interventions to help owners reduce perceived barriers, increase self-efficacy, and improve related knowledge could improve adherence to EDT recommendations and, thereby, increase the diagnostic utility of EDTs.
