I would recommend Petplan as well. I have no dogs with them at the moment (I just can't afford it with two dobes and 8 dogs altogether) but have had in the past and they were excellent :-) Right now I'm with Animal Friends and Aviva, Aviva are ok but not massive cover which might be a problem; AF also ok, only had one major problem which I'm having right now, which is because Remy has so many exclusions, they're trying to get out of his latest condition.
The excess is steep too - £99 + 35% as soon as the dog hits 8, that is my one major gripe with them. I know other companies add percentages but to do it for every dog at the same age, I don't like, especially when a lot of dogs live well into their teens these days. But, they do cover older dogs with new policies and don't restrict them so that is a big plus - they covered my 10yr old rott X last year and have just paid out for her only claim (cancer) with them including their percentage of the euthanasia, which I think is unusual among insurers with older dogs.
So, pros and cons with them. All things considered if you can afford it, I'd go for Petplan. My dog with them did get a percentage added but only once she turned 10, and it was 20%.
