Dosage for Puppies
Virtually all puppies suffer from roundworm infestations. They're either born with roundworms or get them by nursing infected mothers. Roundworms migrate from the blood through the lungs into the digestive tract. Puppies that aren't treated can develop pneumonia, become malnourished and fail to thrive.
If you're a breeder, the manufacturer recommends treating your puppies with liquid Panacur Small Animal 2.5 percent (10 percent for large puppies) at two and five weeks, with a third treatment before the puppies go to new homes. Treat puppies remaining with you at eight and 12 weeks and those kept around other dogs long-term every six to eight weeks on a continuing basis.
If you've brought a new puppy home and it's not around other dogs, worming it every three to four months should be adequate. Administer Panacur liquid by mouth after your puppies have nursed. If they're weaned, mix the liquid in their food right before they eat. Give puppies under six months 2ml per kg (2.2 lbs) of weight. Give puppies weighing 9 to 18 oz. 0.5ml per dose; puppies 18 to 2.2 lbs, 1ml; puppies 2.2 lbs to 3.3 lbs, 2ml; and puppies 3.3 to 4.4 lbs, 3ml. Puppies weighing 4.4 lbs should get 4ml, and an additional 2ml for every 2.2 pounds over that. Dose your puppies once daily for three consecutive days.
Dosage for Adult dogs
Mix 4ml of Pancur Small Animal 2.5 percent liquid (10 percent for a large breed) for every 2.2 lbs of your adult dog's weight in his food before feeding or administer it by mouth after your pet has had a meal. Give only one dose.
Treat your dog whenever he's infested with parasites. Otherwise, if your pet has little exposure to other dogs, treat him every three to four months. If your pet is kenneled, dose him with Panacur every six to eight weeks.
Dosage for Pregnant Dogs
Use Panacur Small Animal 2.5 percent (10 percent for large breeds) to keep your pregnant bitch from passing roundworms to her litter either pre-delivery or through her milk. Start on the 40th day of her pregnancy and continue until two days after she delivers. That should be about 25 days.
Give her 1ml of Panacur for every 2.2 lbs of body weight. That's 4ml if she's between 4.4 and 8.8 lbs; 8ml if she's 8.8 to 17.6 lbs; and 16ml if she's from 17.6 to 35 lbs. Mix the dose in her food right before she eats or administer it orally after she's eaten.
