“…No diet differences were noted in whole blood taurine. The current study results are similar to those in other studies using various dog breeds which analysed diet effect on plasma and whole blood taurine concentrations (Donadelli et al, 2020; Freid et al, 2021;Owens et al, 2023;Pezzali et al, 2020;Singh et al, 2023). However, a study in golden retrievers noted a decrease between dietary groups in whole blood taurine but not plasma taurine (Ontiveros et al, 2020).…”

Little is known about how plasma and whole blood taurine and plasma carnitine correlate to concentrations in skeletal and cardiac muscle and the effects of diet in dogs. The purpose of this study was to evaluate the correlation among plasma, skeletal and cardiac muscle carnitine and taurine and whole blood taurine and determine the effect of diet. The study protocol was approved by the Pet Food Solutions Institutional Animal Care and Use Committee. Thirty‐three mixed‐breed hounds and 32 beagles were evaluated at Day 0 then removed from their baseline diet and randomized to a test diet: high animal protein, grain‐inclusive (HA‐GI), low animal protein, grain‐free (LA‐GF), low animal protein, grain‐inclusive (LA‐GI), or high animal protein, grain‐free (HA‐GF). Blood was drawn every 30 days and endomyocardial (mixed breeds only) and skeletal muscle biopsies were collected at Days 0 and 180. The correlations between plasma and whole blood taurine, or plasma carnitine and skeletal and cardiac muscle concentrations were weak (p < 0.01–0.05). Mixed‐breed hounds had increased (p = 0.029) whole blood taurine compared to beagles. Plasma taurine was lower with diet HA‐GF, (p = 0.009) however, all diets had increased taurine from Day 0 and were, on average within the laboratory reference range. Dogs fed the HA‐GI diet had increased cardiac muscle carnitine esters (p = 0.014). Increased carnitine esters were also appreciated in cardiac muscle in all diets from Day 0 to 180 (p = 0.0001). On Day 180 mixed‐breed hounds had increased skeletal total carnitine (p < 0.001) compared to all time points and breeds. This study observed no correlation between plasma, whole blood, skeletal and cardiac muscle taurine concentrations but noted some effects between time, breed and diet.
