Does it matter how old you are in order to bring your dog here?

You can be any age to bring your pet in, but if you are under 18 you will need to bring your parent or guardian with you. Thank you Katrina

Well I would think you must be an adult but don't know that for sure.

I'm confused about your question, but as long as you're able to handle the financial responsibility of a pet, you can take it to any vet. Including this one.
