Insured two dogue de Bordeaux's with Tesco until one passed away recently. Shortly after this tescos without any explanation, reason or apologie. My monthly bill was increased from £36 to £68 and for one dog. Tesco's were contacted but were not in the slightest bit interested. Since then I have changed and gone with covermypet.co.uk only £14. per month, no problems so far but will review after submitting a claim.
