It is derived from a preprohormone precursor that is synthesized in the hypothalamus and stored in vesicles at the posterior pituitary.

You should also invest in some flea control products ($100 on average). A routine checkup is also recommended and will cost between $50 and $150. Your vet may recommend a few supplements and vitamins, which can add up to $50 per year.
Depending on what vet's cost is how much you'll pay. Where I live the office visits cost between $25 and $47 and this includes physical check-up. Since Specky is new to you and he is an older pup I would suggest having the vet do blood work too, which will add between $60 and $100 to the bill.
