K9 Advantix II I just ordered this online because Sadie gets a tick about every time she goes outside. However, I have since read posts on another website about dogs having seizures. Should I not give to her? She will be 1 year old tomorrow and weighs 4 lbs. 11 oz. I ordered the one that goes up to 10 lbs. I ordered it because it also covers mosquitos, and we have so much water this year. |
