My dog is over 132 lbs. How do I give flea & tick treatment?

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 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.

I wouldn't recommend using it on Sunny since she weighs less than the dose range. While dogs aren't as sensitive to flea treatment overdose as cats are, the potential is still there to cause toxic symptoms such as muscle twitches and loss of coordination. It's best to strictly follow the weight guidelines to prevent any toxicity from occurring. I would exchange the Frontline for a dose in her weight range.

Thank you for submitting your question regarding Lupin. I recommend using Vectra 3D. This is a topically applied medication. The pests are repelled or killed on contact. This means the pet does not need to be bit for the medication to work as is the case with oral medications. It is a broad spectrum product including repelling mosquitos. This helps with heartworm prevention as well. I hope this information helps!

Sentinel has no tick coverage and does not kill fleas. It only sterilizes the eggs. I always go up a size to be safe as most dogs gain weight but rarely lose weight. It has a good safety margin so using the 25-50 pounds medicine would be best. You will continue to need the Simparica or nexgard with this

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!

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.
