We have a dog and travel to San Juan 2-3 times a year. We looked into flying but it is expensive and restricted to certain airports as well as only being available with the non-budget airlines. You would also need recommended crates suitable for airline travel. https://www.skyscanner.net/news/airline-pet-fees has good info.
We looked at the Plymouth - Santander ferry route but also quite expensive and the pet friendly cabins are very limited and never seem to be available. You then still have all of Spain to travel across.
Another option is to use a pet transport service that will transport your pet in specialised vans from UK to spain, again not cheap but does allow you to fly. Try Paws Pet Transport Ltd (Facebook best to contact them). There are others as well that provide a similar service.
Our solution is to use Eurotunnel and drive taking 2 overnight stops, using French and Spanish autoroutes (partial toll, payable by cards at automated toll booths). Both French and Spanish autoroutes are very quiet compared to UK motorways and have regular areas that are good for breaks and dog exercising.There are websites that enable you to find non toll driving routes but obviously this can mean longer journey times.
We also use Booking,com to find and book pet friendly hotels or B&B's, the number of stops is up to yourselves and how long you are happy to drive each day. It is about 1350 miles from Eurotunnel to San Juan, there are many different routes that you can try out.
Remember also to make sure you have in you car the French and Spanish requirements (e.g. warning traingles, .hi-vis jackets) the AA or Halfords websites can tell you what you need to have with you.
If you do come without your own car also check whether hire car companies allow pets, not all do.
Finally make sure that you follow the pet passport rules in particular for return to the UK, we use a vet in Aguilas to complete the return requirements.
Good luck
