Hi! I have pet insurance for my yorkie. It's through PetCare. I pay $18/ month and have fairly basic coverage, but mine also includes a tenant package since we are currently renting. It will cover damages he might cause up to $700. Depending on what your situation is, the PP suggestion about putting $$$ aside each month in a special savings account could be a good option too. In my situation it made more sense to get the coverage. We had to put a claim in a few months ago when Davis licked all the adhesive off of a hook for hanging christmas decorations and started vomiting and we took him to the vet. We just faxed it in and they sent us a reimbursment check a few weeks later.
I signed up online and haven't had any problems since. This is the link
