“…Commercially available accelerometers designed for use in dogs have gained popularity as a means to track daily activity and monitor overall fitness and health. Accelerometers have been utilized to objectively measure physical activity and track‐specific movements in dogs involved in studies on behavior, pruritis, osteoarthritis, and weight loss . The aim of our study was to evaluate the use of accelerometry to detect seizure activity in dogs.…”

Background: The majority of dogs with idiopathic epilepsy continue to have seizures despite appropriate treatment.Objectives: To assess the use of a commercially available, collar-mounted accelerometer to detect generalized seizures in dogs.Animals: Twenty two client-owned dogs with idiopathic epilepsy.Methods: Six-month prospective clinical study during which dogs wore a collarmounted accelerometer. Seizure documentation was based on owner observations and video recordings. The accelerometer used a predefined algorithm to detect seizures in the first study phase, and an individualized algorithm in the second study phase. Caregivers completed a quality of life (QoL) questionnaire at the initial and final study visit.Results: Using the predefined algorithm, the accelerometer detected seizures with a sensitivity of 18.6% (95% CI [13.4%, 23.8%]) and mean false detection rate of 0.096/ day. Values did not change significantly with use of an individualized algorithm (sensitivity 22.1%, 95% CI [15.1%, 29.0%]; false detection rate 0.054/day). Mean composite QoL score was significantly improved at study completion (50.42) compared to study initiation (39.53; P = .005), and this change was moderately correlated with a change in weekly exercise (r = 0.46, P = .05).Conclusions and Clinical Importance: Generalized seizures in dogs can be detected with a collar-mounted accelerometer, but the overall sensitivity is low.

“…The HDD diet is designed to contain whole egg, antioxidants and sources of polyphenols as ingredients chosen for their ability to improve skin barrier function and lower inflammation canine AD (WERNIMONT et al, 2018). In 2014, Plevnik et al reported low plasma vitamin E levels in dogs with AD (PLEVNIK et al, 2013) and supplementation with 8.1 IU/kg vitamin E once daily orally reduced the clinical scores in AD dogs (PLEVNIK et al, 2014).…”

“…The Hill's Derm Defense (HDD) diet contains a proprietary blend of whole egg, antioxidants and sources of polyphenols. This combination of ingredients is claimed to have antioxidant activity, help modulate the immune response to allergens, stabilize mast cells and decrease histamine and cytokine release (WERNIMONT et al, 2018). A recent open-label pilot study reported reduced scratching in six atopic dogs after HDD diet was given for 4-8 weeks, however, concurrent anti-inflammatory drugs for control of AD were administered during the study (WERNIMONT et al, 2018).…”

The effect of anti-inflammatory and anti-oxidant diet on immediate and late-phase cutaneous allergic reactions in healthy dogs

Canine atopic dermatitis (AD) is a highly pruritic and inflammatory skin disease that affects 10-15% of the canine population. The goal of nutritional management for canine AD is to inhibit the inflammatory response, stabilize the skin barrier and support skin and coat health. A new veterinary-exclusive pet food, Hill's Derm Defense (HDD) diet, has been designed for skin and coat health benefits as well as immune modulation in canine AD. This study aimed to evaluate the effect of administrering an oral HDD diet for 6 weeks in suppressing histamine, compound 48/80 and anticanine IgE antibody-induced global wheal scores (GWS) and late phase reactions (LPR) in nine healthy dogs. On days-10 (baseline), 25 and 46 (3 and 6 weeks of only HDD diet treatment) and day 60 (return to baseline), intradermal injections of histamine, anticanine IgE and compound 48/80 were performed on the right lateral side of the thorax in all the dogs. None of the dogs showed any side effects during the study and the HDD diet was well tolerated by all the dogs. There was no significant reduction in histamine, anticanine IgE and compound 48/80 GWS and LPRs with the HDD diet treatment compared to baseline (day-10) and return to baseline (day 60). This research suggests that HDD diet does not exert inhibitory and anti-inflammatory effects on histamine, anticanine IgE-and compound 48/80-mediated skin reactions in healthy dogs. Future studies should assess the clinical efficacy of the HDD diet in controlled clinical trials of dogs with AD.

Objectives: To compare physical activity and length and quality of sleep between brachycephalic dogs and a control population. Methods: Brachycephalic and control dogs were prospectively enrolled. Length of activity and sleep were determined via accelerometer use. Owners completed a questionnaire regarding typical daily activity, sleep patterns and an ‘owner reported breathing score (ORBS)’. One hour of normal home sleep was recorded for each dog, and a veterinary observer subjectively scored the dogs' sleep quality. Results: Twenty brachycephalic and 15 control dogs were included. There were no differences between age and weight. Owners reported brachycephalic dogs to be less active (p = 0.022) and have higher ORBS (p < 0.001) compared to control dogs. Brachycephalic dogs had increased sleep disturbances compared to control dogs (p = 0.001), and video sleep score was positively correlated with increased sleep disturbances (r2 = 0.47, p = 0.007). There were no differences in active and sleep times based on accelerometry between groups. Conclusion: Brachycephalic dogs have more disturbed sleep, which may have negative implications on welfare, but there were no differences in activity or length of sleep between groups. There is evidence that signs suggestive of brachycephalic obstructive airway syndrome (BOAS) as assessed by ORBS is correlated with poorer sleep quality, indicating that reduced sleep quality is part of BOAS. Owners may underestimate disturbed sleep or may perceive disturbed sleep to be normal.
