Do rabbits need monthly worming?

  I have a Netherland Dwarf which i had for almost a year now. When i bought him, the shop assistant told me that my bunny need to be wormed every three months. I've wormed him 1 time and now i 've to worm him again. I find it very difficult to worm him as whenever i try giving him the medicine in a syringe, he rejects it. Also when i mix the liquid medicine in his food, he does not want to eat it, even when i mix it in his favorite treats. The liquid is sweet, but he just doesn't like it. I was wondering if he actually needs worming as when i check some sites, they said it was not necessary. My bunny lives indoors with me and i have no other pets in the house. If it is not necessary, i would not bother and save my bunny the stress he has to go through. But if he has to, is there any better way to give him the medicine?
No , he does NOT need to be dewormed that often! Only deworm if your vet has checked a stool sample and recommends a specific treatment.
Nope rabbits definitely do not need to be wormed unless they actually have worms. I wouldn't worry about it at all if your bun is an indoor rabbit.
No, he does not need to be wormed regularly, only if he actually has worms.
Yeah a rabbit should fit on an oven tray nice and easily add a bit of seasoning, just pop him in let him warm up then take him out then tuck in to lunch
