Go for the source. Even after your pet is lice-free, she can still be reinfested by lice lying in wait on floors, carpet or bedding. To prevent this, it's a good idea to wash all your pet's bedding, says Dr. Logas. In addition, grooming tools, kennels or pet carriers should also be scrubbed clean, either with a mild bleach solution or with soap and water, she says. Stop the itch.
Vets recommend giving one to three milligrams for every pound of pet.
Check with your vet for precise dosing instructions. Soothe her with supplements. Cats, puppies and dogs under ten pounds should be given half a tablet daily. Larger pets can take a whole tablet. One louse doesn't eat a whole lot, but when the louse is lice, your pet could literally be eaten alive.
