From Mothership: Another dog was abandoned over the weekend. What are some of the costs that people don't expect from pets?

Definitely vet costs. These are unexpected, and if your pet has an ailment that requires repeat visits to the doctor, then prepare to fork out a hefty sum over time.

Additionally, surgery costs if required.

Food costs, if your pet happens though be fussy and does not eat the food you like.

Furniture costs, if your pet damages some expensive wood furniture.

Or random costs, if your dog pees on your expensive shoes, for example ;)

Vet costs. One trip to the vet will easily cost you $100.

And if your pet breaks a bone or gets very sick set aside $1000, minimum. Likely will be more for broken bones.
