How to refill Heartgard Plus for my dog without a vet visit?

Heartgard plus is a prescription only medication, so you need to get a script from Akita's vet in order to get it. You can call and ask them to write a script for it if she's been seen by the vet within in the last year. Otherwise, you will have to make an appointment.

Heartgard, Interceptor, Bravecto, Frontline: Which is best for my dog?

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

What are good Heartguard alternatives for my dog's heartworm?

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.

Choosing flea, tick, heartworm meds: Revolution, Advantix, Heartgard?

Congratulations on your new dog! I like Revolution if you are looking for a topical product. It consistently works well and is well tolerated. If you like the idea of an oral product better, I like Trifexis (it’s another all in one product). Sometimes though the pets can smell the Trifexis and they won’t eat it. In that instance, I like Simparica and Interceptor. My personal preference is oral products. I hope this helps and please feel free to post any additional questions.

Can my dog take Heartgard with Clavamox and FortiFlora together?

Hello and thank you for reaching out to Boop by Petco. Yes, it is perfectly fine to give Biscuit her usual monthly Heartgard dose. This should not have any effect on the other medications she is taking. I hope this is helpful!
