Is it safe to use Nexgard and Seresto collars on my dog at once?

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 68 lbs

We just started our dog on nexguard, can we still use his Seresto collar at the same time?

I would not use these two products consecutively. Their combined used hasn't been studied much, but it is just safe to use only one flea/tick prevention in this case. Nexgard is a very effective product, so he should be fine going forward with just this one on board. I hope that things go well for your Mac going forward. Best wishes and take care. : )
