How do dogs get fleas?

Fleas can pass easily from dog to dog. If you take your dog to the dog park where other dogs who have fleas have played, it’s likely that your dog will pick up fleas there, for example. If there are dogs with fleas in your vet’s waiting room, your dog can pick up fleas there. Fleas can jump from dog to dog or, if they’re in the floor, they can easily hop on your dog and hitch a ride back to your house.

Once there are fleas on your dog, the dog will scratch and chew them when he can. Fleas that are swallowed form part of the tapeworm lifecycle. Once digested, the flea will release a young tapeworm in your dog which will feed in your dog’s small intestine. As it grows it will break off in tiny segments that look like grains of rice and be passed in your dog’s feces. You can see them in your dog’s poop. If a dog eats or bothers another dog’s poop that contains these tapeworm segments, he will start the tapeworm cycle in his own intestines. So, keep your dog away from the poop of other animals.
