Dr lisa tomkins' research has provided fellow researchers with important insight into the different expressions of motor, structural and sensory lateralisation in domestic dogs she has certainly added significantly to the landscape for future work in this area of study.
Domestic dogs exhibit extensive morphologic variation, and many behavioral traits vary in their frequency of occurrence based on height and weight ( mcgreevy et al, 2013) most studies have focused on forelimb motor tasks, including the first-stepping test ( tomkins et al, 2010a) and paw preferences ( wells, 2003batt et al, 2009marshall-pescini et al, 2013.
As neurological grades were similar between our cats and those of the previously published literature, the greater survival rate in our study may be a result of the lower number of cats with pelvic limb lower motor neuron (l4–s3 spinal cord segments) signs and/or a longer recovery time being permitted by the owners of our cats. Although the full cohort (n = 114) of dogs participated in the kong test (motor lateralization) and hair whorl assessments, only a portion of these dogs were assessed in the first-stepping test (n = 113 males, n = 52 females, n = 61) and for sensory lateralization (n = 76 males, n = 34 females, n = 42.
Another study in domestic cats found that cats sometimes appeared to be ambidextrous and used either paw however, the more motivated the cat was to reach a treat, the more it tended to use a preferred paw. The domestic dog, canis familiaris, has been shown to display lateral bias in the form of paw preference at the level of the individual , with several, although not all (eg, branson and rogers, 2006 poyser et al, 2006 tan and caliskan, 1987) studies, hinting at a population-level bias centering around the animal's sex, with males being more likely to use their left paw and females veering more towards using their right paw (mcgreevy et al, 2010 quaranta et al, 2004 wells, 2003. Laterality has been linked to personality in some species (eg, fish – brown and bibost, 2014 cats – mcdowell et al, 2016), including, more recently, dogs (barnard et al, 2017), with authors finding a strong relationship between traits associated with stronger emotional reactivity (aggressiveness, fearfulness, sociability) and ambilaterality.
Based on the number of neurons found, they speculated that dogs have roughly the same intelligence as raccoons and lions, while domestic cats have comparable intelligence to bears.

However, the same species may also display a limb preference at the level of population or at the individual level depending on the task, as found in monkeys [66,67], cats  and sheep  motor lateralization in dogs is stable between breeds and over time [41, 46] but variable between sexes. This essay illustrate the need of more standardized methods of motor laterality assessment so that comparison can be made between populations sampled. Previous studies of motor laterality in dogs have produced some conflicting results, with inconsistencies in lateral biases across sexes, over time, and across tasks the current study modified published food-retrieval and tape-removal tests before applying them to 43 dogs.
