Your dog is so handsome! Both Heartgard Plus and Tri-Heart Plus protect against heart worms, but I personally like Heartgard Plus best. As of yet, we have very little research on CBD oil in veterinary patients, so we cannot make any recommendations one way or the other about this product - we do not know what an appropriate dose might be, and if there are any potential health concerns or drug interactions in dogs. In addition, because it's a schedule 1 drug, it's illegal for us to prescribe or recommend. I hope this helps!

You did exactly the right thing by calling around to vets to ask for help right away. It's always best to check when you aren't sure, and are worried about your pet. The Triheart dose that we give dogs for heart worms has very small doses of the two medications that are in it. Ivermectin is one of the medications that is in the Tri heart. The dose is 68 micrograms. Veterinarians use this medication also to treat dogs with skin mites and use a dose over 100 times the dose in one heart worm preventive tablet. Therefore, even if she would have eaten two or three boxes of the Triheart she should be very safe and there is not any risk of an overdose of the ivermectin. The other medication is called pyrantel pamoate which is used for deworming of intestinal parasites. This medication has a very large safety margin also, and can be given at 10-20 times the normal dose without any risks of toxicity. Therefore, just like with the ivermectin in the Triheart Plus, I would not expect any potential

Hello. This is fine to use. I would not recommend giving both of these on the same day. Give one on the first of the month & the second on the 15th so there are no drug interactions. Thanks for using Boop by Petco.

Tri-Heart is generic Heartgard and is just as effective. I am not sure why your vet won't prescribe it for you. You cannot buy any heartworm prevention over the counter so you will need a prescription. I suggest you bring your dog to one of the VETCO vaccine clinics at your local Petco stores (see schedule below). Bring proof of his last negative heartworm test and they can give you a prescription for the Tri-Heart. There is no charge for the exam. Just the cost of the medication. Hope this helps!

Fortunately, there are a number of heartworm preventatives similar to Heartgard, including TriHeart Plus and Iverhart. Other options for heartworm prevention have different active ingredients and include Trifexis, Interceptor, Sentinel, Revolution, and Advantage Multi. Simba's vet will be able to prescribe another option and make sure that Simba has had a recent heartworm test.
