Tony,
But you are both studying Spanish!
All the doctors speak a degree of English but choose not to. They would not be able to attend medical conferences otherwise,etc. where the common language is English. Besides alot of their final text books are in English and are not translated. Furthermore, all the medical journals  and updates are circulated in English.

The doctor in Aldover speaks quite good English and understands it very well too. He is  a jovial guy.

Failing that Tony I can recommend a very good vet who speaks English...lol
;)
