the kennel club do breeders insurance it is really good and it also covers pups in the litter until they are 12 weeks old. you can also cancel it when it is not needed as well, i have used it for my last few litters.
Karen, do I understand you right that you can take the insurance up for the period and then cancel? So could take it up for lets say 3 months and cancel? If this is the case I'll be first in the queue after my last litter and huge vet costs :)
I do this all the time Noora, and have done it for the last few litters, never had any objections, it covers just about everything even fertility testing, and the pups until they are twelve weeks old. i usually start it the month before the bitch due to be mated and then for 12 weeks after.
https://www.kcinsurance.co.uk/home just did a quick quote on one of my girls and it's £35.24 a month with a 10% excess and it covers up to £5000 which includes fertility tests and c-sections
