How many 45mg Program flea pills should I give my 100-pound dog?

Thank you for submitting your question regarding Sophie. First, you need to ensure the flea medication is labeled for use in puppies. Second, if you do not give medication for the correct weight, it will likely be ineffective. If she already weighs 30 pounds and the medication only covers up to 25 pounds, you will be under dosing her. I hope this information helps!

In most cases, administering the larger dose would be recommended. The one caveat is that some cattle breeds are sensitive to invermectin. If the medication contains invermectin and Addie happens to be a dog with a sensitivity it could result in neurologic symptoms such as seizures. If the medication does not contain invermectin, it should be fine to administer the flea medication for dogs over 55.5lbs.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! The Advantus flea pill is once daily. This medication is best used to help kill what is on the dog. I wouldn't use it to prevent fleas as it is expensive to give once daily long term. Once a month Nexgard and Simparica are less expensive and are only given once a month. Also Bravecto is one tablet every 3 months and is about $50 every 3 months. I would spend your money on one of those products. The flea life cycle is 21 days so you would have to give the Advantus daily for at least 3 weeks. But once you stop there is nothing preventing more fleas to jump back on him. I hope this helps!

What breed of dog do you have? I suggest you call the manufacturer of the flea and tick treatment you have on hand. Look on the packaging for the phone number for customer service, or the URL. They should have a customer service number on their web site. This is what I would do as a vet as well, as it is NOT possible to just add medication on for a higher weight. Most large dogs will need less medication per/lbs as the weight increases.

You should give him the appropriate size. If you don’t give him the appropriate size you don’t get the full course of action. You may talk to your veterinarian and see if they can exchange the product for you. All clinics that have different policies. Please feel free to post any additional questions.

Thanks for using Petco Pet Education Center, formerly Petcoach! You are correct- Cody will need the 560mg size. It won’t hurt to give the smaller size but it may not be totally effective. Or you can contact your veterinarian and see if you can switch out the dose for the correct size. Good luck and kisses to Cody!

Hello. It would be best to make sure your pet gets the correct dose so the first thing I would try is to see if Costco will exchange the Nexguard for the next higher dose. If not, I would just give your pet 2 of the ones you have. The problem with just breaking off a small piece is the unequal distribution of the product in each chew tab. You may wind up not giving enough. The size you have contains 68 mg of the active ingredient & the next size up that you need ( 60.1 pounds & up ) contains 136 mg. So, 2 tabs are appropriate.
