Reliability, repeatability, and age associations of the dogSIT (dog Smell Interaction Test) battery in untrained companion dogs (Canis lupus familiaris).. Current olfactory tests for untrained dogs have limitations due to use of a single odorant, requirement for ambulation, and potential for vision interference. We hypothesized that our new dogSIT odorant test battery measures would be reliable, repeatable, and age-associated in untrained companion dogs. Gently restrained dogs were presented with 18 odorants (in 9 pairs, one pair was subsequently excluded from analysis); odorants were contained in identical stainless-steel tea-balls. Odorants were presented for 30s in a habituation-dishabit…

Dog food is specifically formulated food intended for consumption by dogs and other related canines. Dogs are considered to be omnivores with a carnivorous bias. They have the sharp, pointed teeth and shorter gastrointestinal tracts of carnivores, better suited for the consumption of meat than of vegetable substances, yet also have ten genes that are responsible for starch and glucose digestion, as well as the ability to produce amylase, an enzyme that functions to break down carbohydrates into simple sugars – something that obligate carnivores like cats lack. Dogs evolved the ability living alongside humans in agricultural societies, as they managed on scrap leftovers and excrement from hu…
