If you do, and the next time I do (I am currently thinking about it again) I suggest buying one and making it a high deductible policy choice to lower the monthly premium. I think even a thousand dollar deductible may make the monthly premium more affordable.
Vet bills can blow you out of the water; but if it is between shelling out thousands of dollars on a surgery or therapy etc or making an insurance purchase every month --I would go for the insurance purchase with a high deductible.
I have always carried insurance on my dogs; they are no longer here after living well into their senior years because I was able to afford the needed surgeries (cancer) and the water therapy/conditioning for arthritis. The insurance was a peace of mind for my pack of dogs. Of course it will not cover a pre-existing condition or there are clauses regarding that. I have used Pets Best, Trupanion and one other I think it was Pet First. Pet First (if that is the name) was difficult to deal with and slow to pay. The other 2 worked well, but there is plenty of follow up involved with the claim filing. They follow up with doctors and hospitals.
I hope you have success with George's treatment. Keep us posted. on edit: sorry, George belongs to another poster. I read about his situation yesterday.
