Is a short-haired dog more susceptible to getting fleas and ticks?

Any dog - short or long-haired - can get fleas and ticks. It might be a little easier to see them on a short-coated dog, but long-coated dogs, it's even-steven. They can all get it.

They do not discriminate, so whether your dog has short hair, long hair, or no hair, they will be there.

Not really. It's just easier for us to identify them if they get on a short-haired dog, but they're not necessarily going to be more susceptible, especially when it comes to ticks. Fleas, on the other hand, in my many years of experience doing this, I tend to see the shorter hair dogs being more likely to be infested than a long, thick-coated dog, like a chow or a Husky or something of that nature. A hair coat can make a difference, but I wouldn't buy a dog based on that information.

Not necessarily. We see fleas and ticks in all types of dogs, regardless of their coat length.
