At risk of sounding like a broken record...
I think Edinburgh (and possibly other Scottish unis for the same reason) are good places for the Biological Sciences option because they give you the chance to specialise once you get there, ie. once you know what you like etc. Edinburgh do honours (last year total specialisation) in Zoology, Developmental Biology and Reproductive Biology which are very animal based, plus the usual Physiology, Pharmacology, Neuroscience, etc. As you go along you narrow off to modules you do, aiming towards the honours course of your choice.
Having said that, as long as you do a certain amount of undergrad physiology, biochemistry, etc, I think the vet schools are happy. RVC asked for the modules I had done (my honours was in Experimental Pathology) and seemed happy enough, even though I by no means specialised in animal stuff.
