Confused (again) by flea treatments and workers

[permaquandry]

So, I frontline-combo'ed the pup 3 weeks ago and is due for give her Milbemax

.........Posted too soon. She is due for her Milbemax wormer on Tues (3 mth intervals).

I've decided start using Advocate which is a combination of anti-flea and anti-worm.

Obviosuly, I cant use another flea treatment for a week or so. Do I not bother with the Milbemax, wait another couple of weeks and then use Advocate or will I be risking worm infestations?

At this time of year use frontline combo every 4 weeks. Pups should be wormed monthly till 6 months of age. If you want o protect against lungworms continue to use milbemax monthly or if this is not a problem in your area every 3months. Hope that resolves your confusion.

Oh gawd, Confused about flea treatments and WORMERS!

I want to stop using Frontline though and go onto Advocate which I believe is a combination of anti-flea and anti-worm (I know the only thing it doesn't cover is ticks but I'm not sure that's a problem where I live).

Advocate doesn't cover tapeworm. If you are switch to advocate you would be okay to wait a week, but you will need to use a tapeworm treatment every 6 months. This doesn't cover you for ticks.
No golden bullet I am afraid.
Since it got it's lungworms licence my preferred solution is milbemax monthly and then a flea and tick treatment inch as Advantix or Seresto (these prevent the ticks from attaching in the first place).
Hope this helps.
