Dogs are of particular interest in studies of frailty due to the similarities they share with people in their environment, lifestyles, and age-related diseases. Materials and methods The aim of this study was to develop a frailty phenotype screening tool, based on previously validated measures in dogs, which could be easily applied in the clinical setting, and which was predictive of all-cause, short term (6-month) mortality. The study was conducted in two phases. In phase 1, a retrospective cohort of 51 dogs was used to identify and evaluate potential measures for the five domains of frailty. This information was then used to develop a simple frailty phenotype based on examination findings and owner directed questions. In phase 2 of the study, this phenotype was evaluated in a prospective cohort of 198 dogs aged 9 years or older from multiple different specialty and primary care services to determine how the phenotype performed across a diverse canine population. Results The developed frailty phenotype was predictive of all-cause, short-term mortality independent of age, sex, or weight (hazard ratio = 4.71; 95% CI, 2.66–8.8). Of the covariates evaluated only breed was significant, with purebred dogs having 1.85 times higher mortality than mixed breed dogs (95% CI, 1.04–3.31). The frailty phenotype performed similarly across all hospital services from which patients were enrolled. Conclusion Based on these findings, the defined frailty phenotype represents a valuable screening tool for early risk identification and intervention, and can aid in clinical decision making for owners and veterinarians. Additionally, it will promote further research into the understanding and treatment of frailty in dogs.}, journal={FRONTIERS IN VETERINARY SCIENCE}, author={Russell, Katharine J. and Mondino, Alejandra and Fefer, Gilad and Griffith, Emily and Saker, Korinn and Gruen, Margaret E. and Olby, Natasha J.}, year={2024}, month={Sep} } @article{luisana_saker_jaykus_getty_2022, title={Survey evaluation of dog owners' feeding practices and dog bowls' hygiene assessment in domestic settings}, volume={17}, ISSN={["1932-6203"]}, DOI={10.1371/journal.pone.0259478}, abstractNote={In-home pet food handling and food dish hygiene practices can have adverse health impacts for both humans and pets. Safe food and dish handling guidelines are not easily evidenced for pet owners. The study was designed to investigate dog owners’ feeding habits and evaluate the impact of the Food and Drug Association (FDA) hygiene protocols on dog food dish contamination. Procedures and surveys were approved by North Carolina State University Institutional Animal Care and Use Committee and Institutional Review Board. Pet feeding and food dish hygiene data were collected from 417 dog owner surveys and 68 food dish swabs. Total aerobic plate counts (APC) were performed on 68 dishes and randomly assigned into Group A (FDA pet food handling and dish hygiene guidelines), Group B (FDA pet and human food handling and dish hygiene guidelines), or Group C (no guidelines). Hygiene protocols were instituted in-home for 1 week, followed by a second APC and follow-up survey. Survey from dog owners-households indicated: 4.7% were aware of FDA pet food handling and dish hygiene guidelines; 36% have individuals ≤ 13 years old and/or immunocompromised; 43% stored dog food 0–5 feet from human food; 34% washed their hands after feeding; and 33% prepared their dog food on human food preparation surfaces. The hygiene protocols followed by Groups A and B resulted in significant decreases in food dish APC (p<0.001; 1.4; (0.9, 2.0); p<0.05; 0.604 (0.02, 1.2), respectively), as compared to Group C (p≥0.05). Hot water (>160° F or 71.1°C) washing decreased APC (p<0.01; 1.5 (0.4, 2.6)) over cold/lukewarm water. In the follow-up survey, 8% of Group A and B respondents reported likely to adhere to protocols long-term.

Pet dogs and humans represent two populations that have experienced a significant increase in average life expectancy over the last century. A higher prevalence of age-related neurodegenerative diseases has been observed across both species, and human diseases, such as Alzheimer’s disease (AD) and amyotrophic lateral sclerosis (ALS), have canine analogs, canine cognitive dysfunction (CCD), and degenerative myelopathy (DM) respectively. In humans, protein biomarkers have proved useful in the prediction and diagnosis of neurodegeneration. Molecular signatures of many proteins are highly conserved across species. In this study, we explored the potential of the neuronal cytoskeletal protein neurofilament light chain (NfL) as a biomarker of neuro-aging in dogs using an ultrasensitive single-molecule array assay to measure plasma concentrations. Healthy dogs of different ages and dogs affected with CCD and DM were evaluated. The mean plasma NfL concentrations in the different age groups of the healthy population were as follows: 4.55 ± 1.70 pg/mL in puppy/junior group (0.43–2 years), 13.51 ± 6.8 pg/mL in adult/mature group (2.1–9 years), and 47.1 ± 12.68 pg/mL in geriatric/senior group (9.3–14.5 years). Concentrations in dogs with DM (7.5–12.6 years) and CCD (11.0–15.6 years) were 84.17 ± 53.57 pg/mL and 100.73 ± 83.72 pg/mL, respectively. Plasma NfL increases in an age-dependent manner and is significantly elevated in dogs diagnosed with neurodegenerative disease.

A two-part questionnaire was designed, bracketing an educational brochure on environmental sustainability and GFDs. The study consisted of an informational brochure and two questionnaire sections, Q1 and Q2. Preliminary information regarding current diets, diet choice(s), views of environmental sustainability, the definition of GFDs, and the likelihood of feeding GFDs were gathered via Q1. Participants then read a factual brochure regarding pet food trends and environmental sustainability. After reading the brochure, participants completed Q2. Pet ownership of the survey population indicated 12/78 cared exclusively for at least one cat, 48/78 cared exclusively for at least one dog, and 18 cared exclusively for at least one dog and one cat. The majority (70/78) of survey responders fed a dry commercial product, 25/78 fed a canned commercial product, and 1/78 fed a commercial raw product. Prior to reading the brochure, 44.9% of participants were able to partially identify a GFD, 47.4% partially defined environmental sustainability, and 19.2% reported feeding a GFD. After reading the brochure, 67.6% of participants were able to identify a more environmentally sustainable diet vs. 55.9% prior to reading the brochure. A paired T-test demonstrated that after reading the brochure, people were significantly less likely to feed a GFD (p < 0.001). When participants already feeding a GFD were isolated, they demonstrated a higher likelihood to feed a GFD both before and after reading the pamphlet than the remaining population; however, the likelihood decreased from 8.4 ± 2.7 to 7.8 ± 2.7. The informational brochure was effective; participants were less likely to feed a GFD after reading the brochure. Although participants considered environmental sustainability important, factors independent of environmental sustainability influenced the likelihood of diet change. Participants already feeding a GFD also ranked environmental sustainability highly but were less likely to consider changing their pet's diet. These preliminary findings identify a need for public education regarding pet food choices that can have environmental consequences.}, journal={FRONTIERS IN VETERINARY SCIENCE}, author={Conway, Danielle M.

Each cat underwent a randomized 2 week crossover period with all bowl systems, allowing a 1 week acclimation period between each crossover. Water intake was measured daily by bowl weight, accounting for spillage and evaporation. USG and urine volume were measured daily, whereas other urinary parameters were measured at various time points throughout each 14 day crossover period.ResultsFourteen cats completed the study. Average daily water intake (ml/kg/day), urine volume, USG and urine RSS for struvite and calcium oxalate were not significantly different between water bowls. Uosmol was significantly higher in C compared with S and FF bowl systems ( P = 0.009 for both). Three individual cats demonstrated a significant water bowl preference (Cat 4: C >S, P = 0.039; Cat 10: FF >C, P = 0.005; Cat 11: S >C, P = 0.037).Conclusions and relevanceOverall, water bowl type had no appreciable effect on water intake. Uosmol was the only urinary parameter found to be significantly different, and was higher for the C bowl. The implication of this is unknown, considering water intake did not differ significantly between bowls. Alternative methods to increase water intake should be implemented beyond providing unique water bowls in patients where augmented water intake would be beneficial for disease management.}, number={8}, journal={JOURNAL OF FELINE MEDICINE AND SURGERY}, author={Robbins, Michael T. and Cline, Martha G. and Bartges, Joseph W. and Felty, Erin and Saker, Korinn E. and Bastian, Richard and Witzel, Angela L.}, year={2019}, month={Aug}, pages={682–690} } @article{gaylord_remillard_saker_2018, title={Risk of nutritional deficiencies for dogs on a weight loss plan}, volume={59}, ISSN={["1748-5827"]}, DOI={10.1111/jsap.12913}, abstractNote={Objectives To determine how general practice veterinarians make weight loss recommendations for dogs and if nutrients become deficient when following these recommendations.

A cursory diet history indicated that the dog had been fed a raw meat–based diet. Clinical Findings—Initial evaluation of the dog revealed small physical stature, thin body condition, and signs of cranial cervical myelopathy. Radiographically, diffuse osteopenia of all skeletal regions was identified; polyostotic deformities associated with fracture remodeling were observed in weight-bearing bones, along with an apparent floating dental arcade. Hypocalcemia and hypophosphatemia were detected via serum biochemical analyses. The dog's diet was imbalanced in macronutrients and macrominerals. Treatment and Outcome—The dog received supportive care and treatment of medical complications; neurologic abnormalities improved rapidly without intervention. Dietary changes were implemented during hospitalization, and a long-term feeding regimen was established. Following discharge from the hospital, exercise restriction was continued at home. Serial follow-up evaluations, including quantitative bone density measurements, revealed that dietary changes were effective. After 7 months, the dog was clinically normal. Clinical Relevance—In the dog of this report, vitamin D–dependent rickets type I and suspected nutritional secondary hyperparathyroidism developed following intake of a nutritionally incomplete and unbalanced diet. The raw meat–based, home-prepared diet fed to the dog was not feed-trial tested for any life stage by the Association of American Feed Control Officials, and its gross nutrient imbalance induced severe metabolic, orthopedic, and neurologic abnormalities.
