I just read the thread from Orpexo,--Just coming back from the vet.-- And this may help not only your tortoises but may save you money.I use a Vet that is on your Vet list, But the wrong information is listed for her. Fenbendazole (which is the chemical name for Panacur) can be bought over the counter. Sargents sells it in 1 gram packets for dogs,The formula she worked up for me using the Sargents packets is,--Tortoises need 200mg (or .2g) for every 10 pounds,Then she wrote an example : 70 lb tortoise gets 7x.2g=1.4g, 1.4g= 1.4 packets of 1g packets, can round it 1.5 packets. Repeat this dose in 2 weeks.----------If someone that reads this can post her correct information in the Vet section, It is Dr Molly's Housecall Practice, 8028 Cleveland Dr, King George, VA 22485 Molly M Herdic, DVM 540 538 9414 . She doesn't work out of a clinic except for doing surgery, she comes to your house. Tractor Supply carries several different dewormers for farm animals that contain Fenbendazole,one that got my intrest was apple flavored pellets for horses,but I haven't investigated to see if it could be used on the larger tortoises. I hope this helps Len
