I hereby authorize the veterinarian to examine, prescribe or treat the above-described pet(s). I assume responsibility for all charges incurred in the care of this animal. I also understand that these charges must be paid in full, at the time of release of the pet. I acknowledge that charges may exceed a given estimate. AAH charges 12% per month on all balances over 30 days, and 33% of the balance due will be added if the account is sent to collections.
