Ovarian Suture Granuloma Resembling a Tumor in a Bitch.

Ovariohysterectomy is a common surgical procedure performed on female dogs throughout the world. One rare complication is the development of granulomas as a reaction to sutures. Granulomas can grossly and on diagnostic imaging mimic neoplasia, which can present a diagnostic challenge. We present a rare case of ovarian suture granuloma, which resembled a tumor on diagnostic imaging. A 5-year-old, spayed, mixed-breed bitch was presented for anorexia and apathy lasting for a week. On clinical examination fever, dehydration, enlarged lymph nodes, and a tense abdomen were evident. Radiology and ultrasound revealed a 9 cm x 7 cm mass at the location of the left ovary, presumed to be a tumor. The mass was removed on laparotomy and submitted for histopathology which diagnosed granulomatous inflammation as a reaction to a foreign body (most consistently with suture reaction). The current case presents a rare late complication of ovariohysterectomy in the form of a suture granuloma. The case emphasizes the need for additional diagnostic procedures for etiologic diagnosis of masses encountered in the abdomen, especially histopathology, as diagnostic imaging cannot distinguish inflammation from neoplasia.

The Emergence of SARS-CoV-2 within the Dog Population in Croatia: Host Factors and Clinical Outcome.

Over a year into the COVID-19 pandemic, there is growing evidence that SARS-CoV-2 infections among dogs are more common than previously thought. In this study, the prevalence of SARS-CoV-2 antibodies was investigated in two dog populations. The first group was comprised of 1069 dogs admitted to the Veterinary Teaching Hospital for any given reason. The second group included dogs that shared households with confirmed COVID-19 cases in humans. This study group numbered 78 dogs. In COVID-19 infected households, 43.9% tested ELISA positive, and neutralising antibodies were detected in 25.64% of dogs. Those data are comparable with the secondary attack rate in the human population. With 14.69% of dogs in the general population testing ELISA positive, there was a surge of SARS-CoV-2 infections within the dog population amid the second wave of the pandemic. Noticeably seroprevalence of SARS-CoV-2 in the dog and the human population did not differ at the end of the study period. Male sex, breed and age were identified as significant risk factors. This study gives strong evidence that while acute dog infections are mostly asymptomatic, they can pose a significant risk to dog health. Due to the retrospective nature of this study, samples for viral isolation and PCR were unavailable. Still, seropositive dogs had a 1.97 times greater risk for developing central nervous symptoms.

The Effect of a Moderate Exercise Program on Serum Markers of Bone Metabolism in Dogs.

The beneficial effect of physical activity on the musculoskeletal health in dogs is well recognized, but the level of intensity, duration, and frequency of exercise is not fully described. Measurement of serum markers of bone metabolism (bone alkaline phosphatase and osteocalcin as bone formation markers and C-terminal telopeptide as bone resorption marker) during four months of organized moderate-intensity physical training in Labrador retriever and Golden retriever dogs aged between 11.7-24.4 months, showed variations of bone metabolism. Dogs were included in treadmill running sessions for 25 min, three times per week. Blood samples were taken at the beginning of the program (baseline), after two months (mid-term) and at the end of the study after four months. The values of bone alkaline phosphatase and osteocalcin significantly decreased following two months of exercise program. Bone alkaline phosphatase increased by the end of four-month training cycle, but did not reach baseline value. Osteocalcin levels continued to decrease towards the end of the study. C-terminal telopeptide concentrations did not significantly change throughout the study duration. The results of this study show that aerobic exercise of moderate-intensity caused an initial decrease in bone formation followed by an increase of bone alkaline phosphatase and a further decrease of osteocalcin concentration. The response of two formation markers can be explained by the different stage of osteoblast activity that they express. In summary, moderate exercise resulted in no change in bone resorption, and a mild bone formation in young developing dogs.

Animal assisted therapy and perception of loneliness in geriatric nursing home residents.

Use of animals for therapeutic purposes, animal assisted therapy or AAT is a method for improving quality of life for long-term inpatients. The object of this paper was to evaluate dog companionship as a form of AAT and its effects on perception of loneliness in geriatric nursing home residents. The participants were involved in a six-month program of dog companionship three times weekly for 90 minutes. There were 21 residents included in the program, with a mean age of 80 years. Loneliness was measured by the short version of the UCLA Scale of loneliness. Comparison of test results before and after participation in the program showed that dog companionship reduces the perception of loneliness.
