We've been treating dog (18 month old Toller) with advocate - he's never liked it but his reaction is getting worse - last night he was really agitated and was running around the house unable to settle (he's normally really chilled so v out of character). He also swims several times a week plus has hydrotherapy so I'm not sure how much protection he's getting anyway. I'm loathe to use it again so will ask my vet for an alternative. I know frontline is not great any more - is it worth trying bravecto?
