Abstract
The domestic dog (Canis lupus familiaris) species comprises hundreds of
breeds, each differing in physical characteristics, behavior, strength, and running
capability. Very little is known about the skeletal muscle composition
and metabolism between the different breeds, which may explain disease susceptibility.
Muscle samples from the triceps brachii (TB) and vastus lateralis
(VL) were collected post mortem from 35 adult dogs, encompassing 16 breeds
of varying ages and sex. Samples were analyzed for fiber type composition,
fiber size, oxidative, and glycolytic metabolic capacity (citrate synthase [CS],
3-hydroxyacetyl-coA dehydrogenase [3HAD], creatine kinase [CK], and lactate
dehydrogenase [LDH] enzyme activities).
