Vet Q & A
My dog still has fleas. When can I apply Petarmor Plus topical?
The Vetguard plus contains a product that is not good for killing fleas, so it makes sense why you are still seeing them. The Petarmor is a totally different product, so it's safe to use and has ingredients that are good at killing fleas. I'd recommend trying that product and seeing how it goes. The fleas should all be dead after 3 days. I hope that helps and you get this problem under control soon.

Vet Q & A
My dog's flea treatment got wet. Is it effective? Should I reapply?
I would refrain from reapplying this topical product, because you cannot be sure how much of it was rinsed off and it is best to not overdose him. Also the biting and scratching can be normal for any pet that has just received flea preventative if there was a large infestation of fleas. The "itch cascade" as we call it can last even after the parasites are gone, and often pets require a short course of steroids or a steroid shot to stop the itch completely. Your best option at this point, if you still see evidence of fleas or ticks, is to follow up with a medication called Capstar. This is the only flea ridding product that can be used in conjunction with topical flea preventatives, because it does not last in the pets system very long. You can safely redose the Pet armour in 2 weeks time. However I will say I am not a fan of this product and find there are better, more effective ones on the market. For instance, Bravecto, Nexgard, Advantage Multi, just to name a few.

Vet Q & A
Puppy still has fleas after PetArmor Plus & home treatment. What now?
You listed Ruger's age as 12 days, and if that is the case your options are pretty limited. I am guessing though that you meant 12 lbs, and the average German Shepherd puppy would be about 8 weeks old if they weighed 12 lbs. If that's the case you have many more oral and topical options. I often recommend Nexgard, but your veterinarian may have a product that is preferred in you area. You probably need something that will kill fleas quickly, and you may also need to vacuum and bomb your house again. I'd recommend contacting your vet.

Vet Q & A
My dog has fleas after PetArmor Plus. Can I use flea shampoo?
Unfortunately Petarmor Plus is a very poor flea treatment for dogs, and it frequently doesn't work. You can give her a bath with the flea and tick shampoo, but keep in mind it doesn't provide lasting protection. I would give her Capstar. It's a one time pill that starts killing fleas within 30 minutes, and it's safe to give now. You can give Muffin one a day until two weeks have passed since you gave administered the Petarmor Plus. Then it's safe to use another spot on treatment such as Revolution or Advantage. Both are very effective at killing fleas. You will also have to disinfect the environment. 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. Good luck, I hope this helps!

Vet Q & A
Can I give Capstar to my dog after using Pet Armour for fleas?
Yes, you can certainly give Luna a dose of Capstar after applying Pet Armour Plus. The Capstar should kill adult fleas quickly, but will not provide lasting prevention against maturing larvae and eggs. Pet Armour should be able to provide this prevention for the remainder of the month. However, when Luna is due for another dose of flea prevention next month, I would instead recommend using a higher quality product, such as Nexgard, Bravecto, or K9 Advantix II, as I tend to find these products more effective. I hope this helps and that all goes well!
