I hold a BA in a language and area studies (history, politics, social science) and a PhD in political economy (touching on social science), both from British universities belonging to the (research-strong) Russell Group, and I have been outside of academia for many years.
What route might I take towards the goal of researching for a PhD, preferably again at a Russell Group institution in Britain, in canine psychology and behaviour?
(I have read the help file, and felt that giving details of the fields was necessary in order to make clear what I am asking. Advice that is not specific to these fields is very welcome, especially if the size of the gap between them is similar to the size in my case.)
