we have 4 giant breeds, they eat £2-3/day of food, one costed us £3500 at age 4 at hospital in London, another cost £1500 at hospital at Fitzpatricks last year at 4 years old, another is on medication that would cost a normal owner £250/month. (my OH is a vet, so medication is cost price)
If any surpass 10 years old we'll be very happy
