Health & WellbeingI applied pet armour plus to my dog and 3 hrs. later my daughter took him for a walk it started raining do i need to reapply still scratching,biting
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.
