Is it safe to give my dog Heartgard Plus and Credelio at the same time?

Updated on September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Female | spayed | 4 years and 4 months old | 5.3 lbs

I have always used the liquid flea medication that goes between the dogs shoulder blades, and weve never used heartworm medication. we recently got told by our vet that a pill instead of the liquid is alot more effective and she recommended credelio which worked great. I want to start using heartworm medication since it is so important, can we give heartgard plus and credelio at the same time once a month?

Yes! It should be okay to give both pills at the same time. You might want to stagger them the first time by a day or two just in case you happen to see some nausea or other adverse effects, but after that give both at the same time.

    Hi there. If you're asking about Tri-Heart Plus and Credelio, yes - it's fine to use these two medications together. I am not aware of any pet medication called "Credulity," so if you meant something else, please post again with the exact name of the medication.
