My vet advised me to use Advocate flea treatment every month and also Drontal for worming every three months (for my golden). The first few times were fine but now she absolutely hates having it applied, whines and whimpers and backs away in absolute terror - does it sting when applied? She also pants really hard for an hour or so after application and is very sleepy the next day or so.....I'm thinking that this isn't a good reaction and I should find something else for her - but I was also told that Frontline isn't effective any more and that Advocate is about the only effective flea treatment.
Can anyone else advise what worming/flea treatment works for them please?
