I have an elderly dog who is on daily medication for heart, arthritis & epilepsy.
Had some friends travelling to Spain and they were able to buy her medication - prescription free - over there for approximately one-fifth of what the vet here charges.
I got 3 months supply and am delighted with the savings I have made. There are lots of dogs, cats, horses etc on this type of long term medication, so it's worth checking out.
I'm sorry now that I didn't also get them to check out the cost of flea and worming treatment also, but will look into that also next time.
