I will try to get the Panacure... but my mum is coming from Australia soon and can get the Safeguard... so she will try to find out if it can be given to tortoises.
Safeguard = Panacure..
Horse/cattle wormer paste. Not pills.
And its does come in dog stuff too. but prob costs more and might be in pill form.
Contact your Tort Vet for dosage. There are different strengths.
