An earthdog test or earthdog trial tests the working ability and instinct of the small, often short-legged terriers or Dachshunds. [1] [2] [3] These dogs were bred to hunt vermin and other quarry which lived in underground dens. Earthdog den tests involve human-made tunnels that the dogs must navigate, while scenting a rat, "the quarry". The ...
A concretion is a hard and compact mass formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. [1] Concretions are often ovoid or spherical in shape, although irregular shapes also occur.
A concretion is a volume of sedimentary rock in which a mineral cement fills the porosity (i.e. the spaces between the sediment grains). The image shows a Sandstone Concretion in the wall at the beach of Año Nuevo State Reserve. This concretion was too high in the wall to place a ruler, but I estimate it to be about 400 mm long.
Our test dog is very good-natured and puts up with a lot, but she would not allow for the full swabbing time with any of the kits. This is a common experience, so doing some prep work before the ...
The Behaviour and Personality Assessment in Dogs (Beteende och personlighetsbeskrivning hund), commonly abbreviated as BPH, is a behavioural assessment developed by the Swedish Kennel Club (SKK) in May 2012 [1] [2] that aims to accurately describe the personality of a dog irrespective of whether it is a working, pet or breeding dog.

The history of animal testing goes back to the writings of the Ancient Greeks in the 4th and 3rd centuries BCE, with Aristotle (384–322 BCE) and Erasistratus (304–258 BCE) one of the first documented to perform experiments on nonhuman animals.

Field tests and hunt tests are non-competitive activities designed to test a gundog's natural hunting abilities in a field environment without the added pressure of competition. [ 19 ] [ 20 ] Unlike in field trials where dogs compete against each other, in hunt tests dogs compete to pass the requirements of the tests. [ 20 ]
The idea behind cancer dogs is that there may be volatile compounds produced in cancer patients that dogs can detect by scent. In these studies, the compounds are not identified, not tested for, not named. There are many confounders, for example, in the few samples used, there may be other differences being detected by the dogs. [14]
