Both of those should be safe if applied to the outer coat. However, they will not effectively prevent fleas and ticks. The best way to prevent external parasites is by using a product from your vet. There are newer products like Bravecto and Nexgard that are oral tablets that prevent fleas/ticks for 30 days. This is the best way to keep your dog parasite free.
