Is it safe to use flea treatment for a larger dog on my 71lb dog?

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.

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!

Hi there, It kind of depends on the product, but I wouldn't use it on her if it's going to be a slight overdose. Sometimes products have a wider safety margin, but flea products can be toxic at higher doses. Ideally go buy a product that is her size, and that kills adult fleas and their eggs. You can also give her a bath to drown some of them. Sorry you have to deal with that, but congrats on your puppy. Also let the shelter know they have fleas... Best wishes to you and Lucy and thanks for using Pet Coach.

No this is not something i can recommend, i strongly advise switching to a different product as well because frontline is not that effective anyway, i would recommend Advantage spot on, but you must buy the correct weight because if you use a product for a smaller dog it will not work.

No, this would not be recommended. Given the weight difference, you would likely need multiple doses which could easily lead to overdose. Use a product specifically for dogs. Talk with your veterinarian about the safest, most effective options.

Hi there and thanks for posting on Petco Pet Education Center, formerly Petcoach! This is a common question and issue with preventatives in growing puppies. Often times veterinarians may opt for the higher weight range in these preventative products when the weight is borderline between two dosages or when rapid weight gain is expected within the next 30 days. You definitely want to ask Milo's prescribing veterinarian what they think is best for Milo and if going up a weight range would be OK.

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.
