Cali is currently out of her meds and is due in a few days for a re-up. She has been on both Frontline and K9Advantix and so far we have had no problems. I found that Petsmart now sells Advantix OTC and it will be cheaper and more convenient then getting it from the vet. What do all you other east coasters use? I live in a area that has alot of deer unfortunately so I have to keep her on it constantly. Ideas?
