My pig has lice. What oral or topical treatments are safe for pigs?

The best way to treat lice in pigs is with Ivermectin. It is the safest and most reliable drug. I suggest you contact your local vet to get this medication and to get dosing information. Other possible medications that would work: diazinon, lindane or deltamethrin. These medications are harder to find and are considered not as safe. All these medications are ineffective against lice eggs so it is necessary to treat the animals and the environment multiple times.

You can buy some ivermectin at a farm shop and give her an injection with ivermectin. You can also get some diatomacious earth at a garden center and dust your pig with it. This will clog the tracheae (lungs) of the lice and kill them . Make sure you also meticulously clean her bedding and stable and put some diatomacious earth there as well.

Ivermectin in pigs can only be given by subcutaneous injection at the neck, so no you cannot give it to Penelope orally. I would have a friend come over to help hold her so you can give her the shot.

You should only give your pigs antibiotics for a medical reason diagnosed by a vet. Then the length and frequency of dosing will be determined by the severity and type of condition. Usually it involves a daily injection for 5 days up to 2 weeks. Unfortunately I cannot legally give you specific information about prescription drugs, but your vet will be able to advise you. There are various antibiotics and antinflammatories of use in swine.

Frontline, Advantage, and Advantix for dogs are safe for pigs if you follow the weigh dosing. You can get them at your vet's clinic, and I would ask the staff for help with getting the correct dose for Sampson.

What a cute little guy! Mice do get lice, and it's usually because they're in poor husbandry conditions (like being sold for food). This means your mice are likely infected with other parasites like dwarf tapeworm that definitely is zoonotic (meaning it can infect you). You should treat this little guy with Revolution for cats, which is a spot-on treatment you can get from your vet, and use it topically ever 3 weeks until the parasites are gone. Disinfect his cage and throw out all the bedding as well. If you spray the cage/furnishings with fipronil topical spray this helps kill all the eggs and disinfects the environment. Hope that helps, and best of luck!

Typically, unless your piggy comes to you with mange you are unlikely to encounter an infection. This is not true however if your pig is going to be in contact with several other pigs on any sort of regular basis, particularly those of unknown health status. Should your pig become afflicted with this, it is relatively easy to address. The best way is with two injections of ivermectin separated by two weeks. There are two common mites in pigs. The sarcoptic mange mite can be passed between dogs, pigs, and humans. The demodectic mite can not be passed to dogs as it is species specific. Hope this answers your questions and concerns.
