White and light-colored dogs have symptoms of parasites

It is actually easy to find external parasites in white dogs, because the food for external parasites is the dog’s blood, and they always eat it. It's a poop, and it will leave little black spots on the dog's body. If you comb your dog's hair, it's easy to spot. If you want to distinguish whether it's dirt on your dog's body or if it's got bugs, it's easy to do. Just put the little black dots in the water, melt them and see if there are any. Blood color will do. Bloody stools are definitely the result of external parasites, so you should deworm your dog as soon as possible. Training dogs every day

Dark and black dogs have symptoms of parasites

As for dark and black dogs, it is not easy to find external parasites in their feces. There is a small tool called a flea comb, which is a very dense and very fine comb. It cannot comb out the external parasites on the dog, but it can comb out the poop mentioned above. You only need to comb it out and tap it on a white paper, and then identify whether it is dirt or external parasites. The identification method is the same as above.
