Summary

A study was conducted to provide baseline data on pet dog diet and exercise patterns. In addition, the repeatability of a telephone questionnaire to determine these patterns was evaluated. Dogs seen at the Texas Veterinary Medical Center that, were less than 3 years old and of medium, large, or giant purebreeds or mixed-breeds were included. Information was collated about background variables, brands, quantities, and types of foods fed, and types and frequency of exercise. Daily intake of metabolizabk energy, calcium, fat, and protein were calculated from the diet. Sixty-nine dog owners completed the study. Most dogs were kept as pels in an urban/suburban environment Most were also fed diy food. About 60% were fed dog biscuits or some other dog snack or treat, and about half of the dogs in the study were Jed twice daily. Meat scraps and bones were the table foods most commonly fed. Most owners considered their dogs to be moderately or very active. Greater than 70% of the dogs were confined to a fenced yard. About 65% of the owners took their dogs for walks, forty percent of dogs in the study exercised with other dogs daily. More than half of the owners reported playing retrieving games with their dogs, including playing with a flying disk. The questionnaire was shown to be repeatable.

Abstract

OBJECTIVE

To evaluate outcomes of dogs with parathyroid carcinoma (PTC) treated by surgical excision and to describe the incidence of postoperative hypocalcemia, degree of hypocalcemia, duration of hospitalization, duration of calcium supplementation, and survival time

ANIMALS

100 client-owned dogs with PTC admitted to academic, referral veterinary institutions.

PROCEDURES

In a retrospective multi-institutional study, medical records of dogs undergoing surgical excision of PTC between 2010 to 2019 were reviewed. Signalment, relevant medical history, clinical signs, clinicopathologic testing, imaging, surgical findings, intraoperative complications, histologic examination, and survival time were recorded.

RESULTS

100 dogs with PTC were included, and 96 dogs had clinical or incidental hypercalcemia. Common clinical signs included polyuria (44%), polydipsia (43%), hind limb paresis (22%), lethargy (21%), and hyporexia (20%). Cervical ultrasonography detected a parathyroid nodule in 91 of 91 dogs, with a single nodule in 70.3% (64/91), 2 nodules in 25.3% (23/91), and ≥ 3 nodules in 4 (4/91)% of dogs. Hypercalcemia resolved in 89 of 96 dogs within 7 days after surgery. Thirty-four percent of dogs developed hypocalcemia, on the basis of individual analyzer ranges, within 1 week after surgery. One dog had metastatic PTC to the prescapular lymph node, and 3 dogs were euthanized for refractory postoperative hypocalcemia. Estimated 1-, 2-, and 3-year survival rates were 84%, 65%, and 51% respectively, with a median survival time of 2 years.

CONCLUSIONS AND CLINICAL RELEVANCE

Excision of PTC results in resolution of hypercalcemia and excellent long-term tumor control. Surgical excision of PTC is recommended because of resolution of hypercalcemia and a good long-term prognosis. Future prospective studies and long-term follow-up are needed to further assess primary tumor recurrence, metastasis, and incidence of postoperative hypocalcemia.

Abstract

OBJECTIVE

To determine long-term outcomes and factors associated with those outcomes in dogs with gastroesophageal intussusception (GEI).

ANIMALS

36 dogs with GEI evaluated at 16 veterinary hospitals from January 2000 through January 2018.

PROCEDURES

Medical records of included dogs were reviewed to collect information regarding signalment, clinical signs, physical examination findings, blood work and diagnostic imaging results, surgical findings, and outcome. Factors were evaluated for associations with various outcomes.

RESULTS

Median age of dogs with GEI was 13.2 months, and males (72% [26/36]) and German Shepherd Dogs (33% [12/36]) were most common. Vomiting (67% [24/36]) and regurgitation (33% [12/36]) were the most common clinical signs. Ten of 36 (28%) dogs were euthanized without treatment, and 26 (72%) underwent treatment (25 surgically and 1 endoscopically). Twenty-three of the 26 (88%) treated dogs survived to discharge; median survival time was 995 days. At last follow-up, 15 of the 23 (65%) surviving dogs remained alive and 8 (35%) had died for reasons related to persistent regurgitation (n = 6) or reasons unrelated to GEI (2). Of the 10 dogs for which owners were contacted, 7 had persistent regurgitation, the severity of which was reduced through managed feedings. Dogs with acute (≤ 7 days) clinical signs or a previous diagnosis of megaesophagus were more likely to have persistent regurgitation than were dogs without these factors.

CONCLUSIONS AND CLINICAL RELEVANCE

Treatment should be considered for dogs with GEI given the high rate of survival to discharge and median survival time. Although persistent regurgitation was common after treatment, a satisfactory outcome was possible with medical management, including managed feedings and medications.
