We have insured our German Shepherd from when she was a puppy with Tesco. the price increased to an extortionate £632.92 as she is now 11. We made a claim for a lump which had been noted by the vet, however did not require treatment at the time. the lump subsequently required treatment and Tesco refused to pay stating that it was a pre existing condition. whilst I accept that, when the condition was noted no treatment was required therefore what they are implying is that we should have undertaken unnecessary treatment on an 11 year old dog to have a valid claim.
