Quarantine Might Be Necessary for Dogs with Worm
Whether you need to quarantine a dog with worms will depend on the type of parasite the dog is affected by. Generally speaking, dogs affected by intestinal parasites like roundworms, hookworms, and tapeworms don’t have to be quarantined.
Intestinal parasites don’t really spread via close contact. Instead, they have a tendency to spread if a dog was to consume an infected stool. If you have multiple dogs and one of them is affected by an intestinal parasite then make sure that the dogs are getting proper de-worming treatment and the feces are safely discarded until the infected dog fully heals.
Intestinal parasites, however, aren’t the only type of worms to affect dogs. Another common threat to dogs is the heartworm. You may want to quarantine dogs with heartworms but not necessarily due to the risk of spreading to others. Heartworms aren’t considered contagious. Dogs get heartworms from mosquitoes so it’s not necessarily dangerous to have the infected pet around other humans and animals.
That said, you may still want to quarantine a dog with heartworms for a little while in a quiet and calm environment. Initial symptoms of heartworms include fatigue and weight loss. You may want to make sure the infected dog is able to recover a stress-free environment.
