My Husky Kira is 2 years old and weighs 20.75kg and was wormed when I got her on the 31st March and the old owner used Beaphar worming cream which by reading dont think it would be one I would use. I want to use Drontal tablets for worming and would need 2 tablets (1 tab for each 10kg bodyweight)

I know worming is supposed to be done every 2-3 months but wondered when it would be possible to worm her again with Drontal?

I usually use Panacur to deworm my dogs, I can buy it without a prescription. I think you need a prescription for Drontal, and it is effective for tapeworms as well. I'm pretty sure that worming every month will not hurt her. A quick phone to your vet and they will be able to tell you if it is safe or not to worm early.

I use a monthly heartworm preventative that also prevents intestinal parasites like round worm, etc. We deworm her often as well with over the counter meds. I believe you could do it monthly if you wanted to, but IIRC I read that 6 months is sufficient.
