<human>: I have been wanting a dog ever since I moved out on my own 4 years ago. I grew up with dogs and have worked as a dog trainer, pet sitter, and vet tech for the last several years. I've been waiting for the perfect dog at the perfect time. I think this may finally be it.

My neighbors have a puppy (8 mos) heeler mix that is way too much energy for them. She's exactly what I want. However I have to think reasonably about the costs of owning a dog. She's almost a year now, and she's never been to the vet. She is in great shape and has been treated with a lot of love, but she'll need her vaccines and need to be spayed, as well as flea and heartworm medicine. I have no idea how much the first month of owning her will cost me, so i'm hoping to get some wisdom of experienced owners.

Summarize the given text in a few sentences.
