Can my indoor dog still get intestinal parasites?

Yes, unless your indoor dog never goes outside, although I don't think any dogs are like that.

They can. Whether your dog is just going out to use the bathroom, or even if you were walking through a yard and potentially stepped on some dog poop and tracked it in, that is a way that they can get exposed. Or, even if they have fleas, they can get exposed to tapeworm eggs and still have those intestinal parasites.

Yes, your indoor dog can still get intestinal parasites. Even though your dog is indoors, they come into contact with the outside environment when they go out for walks or to potty. They can get parasites like hookworms and roundworms from the grass or by ingesting a live flea. There are some intestinal parasites that are also contagious to people, so we need to be cautious about that. Dogs can get tapeworms when they ingest a live flea, so if your dog is an indoor dog, but they have tapeworms, that means that when they are going outside to go potty, fleas are getting on them and they're chewing at them and swallowing a live flea because that's the only way a dog can get a tapeworm.

Indeed, indoor dogs can still get intestinal parasites. We could potentially bring some of those eggs and that feces in off the street on our shoes.
