My dog used Nexgard, Simparica. Is Credelio safe after FDA warnings?

As you have already suggested, there are no absolutes. All the drugs the FDA mentioned in their recent warning are in the same class, including Credelio. Thus, I would venture to guess that it is unlikely Timmy with have a negative reaction to one but not the other. He does not appear to have a sensitivity to this class of drugs. There are always the off chance of allergies, but these are few and far between. Hope this makes sense.

Can I give my dog Tri-Heart Plus and Credelio 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.

Hartz flea medicine failed. Is it safe to give my dog Credelio now?

Hartz is a very poor product, so I'm not surprised it didn't work for Kalee. I would wait at least two weeks after you applied the Hartz before giving her the credelio, as it's not good to combine flea medications. Remember as well that fleas live in the environment, they only jump on the dog to feed, so you have to disinfect your home as well. Wash her bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. Best of luck, I hope this helps!

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

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.
