Heartgard and interceptor are equal. It is personal preference for your dog and you. Heartgard is a larger, chunky chewable which some smaller dogs may not like to where interceptor is small pile that can be hidden in a treat and raiser to give pickier dogs. Bravecto is a better product as it is a pill form and last for 3 months but frontline is a topical that last for a single month

Thanks for using Boop by Petco! Yes, she most likely will be fine. Just keep an eye on her and let your veterinarian know if you notice anything abnormal in her such as loss of appetite, nausea, vomiting, decreased activity, unsteadiness, and or lethargy. She is likely to be fine. Good luck and have a good night!

One of the active drug ingredient in both meds is milbemycin, so if the allergy or reaction to was that specific drug, it would be better to avoid it. Of course we can't know that for sure. It may be that Rexy is allergic to one of the other active ingredients in trifexis, or to one of the inert ingredients. However, I think the best recommendation would be to use a prevention that does NOT contain milbemycin or praziquantel (the ingredients in Trifexis). Heartgard is a good alternative. Make sure that he is up to date on his heart worm test first. I think its fine to go ahead and get him started on a different heart worm prevention ASAP, even though he just had surgery. I hope that helps you ! Thanks for asking Boop by Petco!

Hi there. While there's technically no reason that these two medications can't be used together, they are both heartworm preventatives - so there's quite a bit over overlap in what they do, and both should not be needed at the same time. If your pup is currently on Interceptor and you want to add a second medication to cover fleas, I would recommend using something like Nexgard or Bravecto - these are flea/tick meds only, so you wouldn't be treating her unnecessarily for heartworms with two different meds.
