Once upon a time,i too used Petplan,but they stuck their premiums up so much the monthly amount was more than my house and car insurance combined.Admittingly at the time i had a Rottweiler which attracted bad press,but it still dont excuse plain old greed.
I switched to Direct Line and used them for years,but i now have a Bullmastiff and recently moved to Tescos who were half the price again.The policy is less i must add as it will only pay illness/accidents etc £2,500 per year,but with how things are-im looking at ways to save money.
Try Tescos!
