About Interceptor Plus (milbemycin oxime + praziquantel) Chewable Tablets for Dogs

What is Interceptor Plus (milbemycin oxime/praziquantel)?

If your dog is only protected from heartworm disease, there’s a gap in their coverage. Close the gap with Interceptor Plus. Interceptor Plus also treats and controls four other major worms including adult roundworm, hookworm, whipworm and tapeworm infections in dogs and puppies. That’s protection against more types of worms than Heartgard Plus. Unlike Interceptor Plus, both Heartgard Plus (ivermectin/pyrantel) and Simparica Trio (sarolaner, moxidectin, and pyrantel chewable tablets) do not cover tapeworm or whipworm.*

When untreated, intestinal worms can cause discomfort and fatigue with diarrhea, weight loss, anemia and more. That’s why Interceptor Plus makes dosing easy and convenient with 5-in-1 protection in a tasty, chicken-flavored chew. No need to hide pills in food-pockets. This chewable heartworm prevention goes down easy and keeps the protection going strong for a month.

Interceptor Plus heartworm prevention is only available by prescription. Dogs must be at least six weeks old and weigh 2.0 - 8.0 lbs. to use this dose of Interceptor Plus.

Never miss a monthly treatment when you subscribe to convenient, regular doorstep deliveries of 1-dose, 6-dose or 12-dose packs. Before starting any heartworm prevention program, it’s important for your veterinarian to test your dog for an existing heartworm infection. At your next visit, tell your veterinarian you want PLUS-level protection for your loyal pup so you can enjoy peace of mind in all of their favorite places – from the backyard to the dog park.

Interceptor Plus is a trademark of Elanco or its affiliates. All other product names are trademarks of their respective owners

*Heartgard Plus protects against heartworm disease, hookworms (A. caninum, U. stenocephala, A. braziliense), and roundworms. Simparica TRIO protects against heartworm disease, hookworms (A. caninum, U. stenocephala), and roundworms.

She loves it and so do we ❤️
[This review was collected as part of a promotion.] In case the picture doesn’t do it justice, she’s loved it since we first unboxed it 😍😂 she loves it and we love that it’s protecting her and not having to worry about her we’re all very thankful for this collar!

Easy and convenient
[This review was collected as part of a promotion.] I tried the Seresto collar on my dog and it worked really well. It was easy to put on and the size fit perfectly. My dog seemed comfortable wearing. It’s easy and convenient option for long-lasting protection.

Easy to use
[This review was collected as part of a promotion.] I used this on my husky and it was easy to put on her. Didn't seem to bother her neck. In terms of being effective I would say it works as no fleas and ticks on her. The scent is a little overbearing and I wish it was lighter. But it didn't seem to bother her.

Worth a try
[This review was collected as part of a promotion.] Easy to apply. It fits my golden retriever easily. Easy to adjust. I hope it works as it is intended to. Supposed to last 8 months which is substantial. Only supposed to bathe your dog once a month with this on.

Good so far
[This review was collected as part of a promotion.] I did receive this product for free from Influenster to review. I kinda hesitated to give this a perfect five-star because I feel like i haven't had enough time to fully test its flea and tick repellent claims. But i did give it five stars because i've had no issues with it so far, and I only have a limited time to get my review in. As far as instructions, there is a booklet in the container that clearly explains how to put the collar on and everything about how it interacts with water and how often bathe your dog. I felt like the booklet was pretty thorough. Getting the collar on was super easy. The size was perfect for my dog. My dog is used to collars and harnesses, so it's not been an issue for him to wear it at all. He's had it on for a few weeks now, and I have noticed no averse reactions in him in any way. I had no reaction to it while putting the collar on. I did wash my hands really well after applying it. Also, my son loves to cuddle with my dog, and it's not like he's rubbing all over the collar, but he hasn't had any issues from being around or near it. Unfortunately, though where I live (we got this delivered in February), it's still cold. We aren't in flea and tick season yet. So i can't tell if this is going to keep them away. I wish I had until the summer to get my review done so I could speak on that in a more informed way. I'm hopeful, though, my Mother in law swear by Seresto collars for her dog. So fingers crossed.

Happy with your collar for my dog
[This review was collected as part of a promotion.] This is going to be perfect for summer time my dog plays outside and this will keep him flea/tick free. Claims to last up to 8 months protecting. It is a perfect fit and I like that this doesn't put my dog at risk of getting side effects which some chewables do.

Keeping them safe
PetMeds always have great customer service first of all. With the Interceptor Plus I know my two are always kept safe from heartworms and other parasitic worms, We live in the tropics, so we need to be cautious. PetMeds always ships so quickly, we are very impressed with their customer service. Have been ordering from them for years.

Poor customer service
I ordered 2 packsofInceptor Plus. Only 1 arrived. I waited a couple days but the other never arrived. When I called customer service, I waited 40 minutes and no one ever answered. I waited another day and called again. After 20 minutes without a person to talk to, I hung up. I left a message on the site and never heard back. I will not be dealing with PetMed again.
