Cognition is defined as; the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses. As we age our cognitive ability declines naturally, however some individuals may experience a rate of decline much greater than expected. This is known as cognitive dysfunction.
Cognitive dysfunction is apparent in a number of species, including; humans, dogs and cats. In dogs, canine cognitive dysfunction (CCD) can be responsible for alterations in normal behaviour, for example, the dog may be less active or show changes in their social interactions with human family members.

Darwinian fitness – The rate of increase of a gene in the population, this is difficult to measure. It describes the capability of an individual of certain genotype to reproduce, and usually is equal to the proportion of the individual’s genes in all the genes of the next generation. If differences in individual genotypes [...]
Tinbergen’s four Questions of Ethology

• Function (adaptation) – This type of explanation for animal behaviour usually concerns a trait that is functional to the reproductive success of the organism [...]
