I was wondering what ingredients do the Johnson dog wormer tablets contain. As my dog has been sick on other worming tablets and i want to compare the ingredients.

Do these require perscription?

fanis

What is the difference between these and the ones that require vet prescription?

  • VioVet Staff

The ingredients differ between prescription and non prescription wormers. Certain worming ingredients can only be supplied under a prescription.
In general there is no over the counter wormer that will cover lungworm, however you can get good wormers that will cover both roundworms and tapeworms over the counter.

Roundworm

Helen

My dog has roundworm. I've seen it twice now in his poo which has been runny. He's been tired these past few days . Today I've given him 3 johnsons worm tablets my question is when do I give him some more as I know the first dose only kills the adult worms ?

  • VioVet Staff

The general advice is to worm once per month if worms are seen. This is especially important in puppies. Once the dog appears to be clear of worms (or at 6 months of age), then every 3 months is generally fully adequate.
