Can Fencing Your Dog Can Protect Him From Parasites?

By Moses Wright

Though a fence will not prevent all parasitic infestations, fencing your dog can protect him from parasites. Car accidents and ingestion of toxic substances in garbage are other dangers that can be prevented by fencing your dog.

The risk for hookworms can be higher if the dog is unfenced and able to go to an area where a dog with hookworms has defecated. The feces or ground around the feces can contain hookworms. The hookworms can infect a dog by burrowing through its skin.

Threadworms also can be acquired through the skin by being contaminated feces, but the feces can be from infected dogs and other animals as well. Threadworms can be passed through feces of infected dogs and other carnivores. Being fenced prevents the dog from being in contact with feces from infected dogs, cats, or wildlife.

Gnathostoma is a potentially dangerous parasite that can infect a dog that eats an infected animal. The gnathostoma burrows through the dog's stomach, travels around the dog's body causing damage before returning to the stomach. Since a dog fence keeps the dog isolated from most other animals, this is another parasitic infection reduced by fencing.

Like the gnathostoma, the spirocerca lupi is acquired by eating an infected animal. Spiocerca lupi lives in the dog's stomach after being ingested. Spirocerca lupi can cause damage to blood vessels and cancer of the esophagus.

Whether the dog is fenced or not, the dog is at risk for certain parasites while the dog is outdoors. Heartworms are spread by mosquitoes which cannot be stopped by dog fences.

The risk of fleas and ticks can be greatly reduced by a fence which keeps the wildlife and other dogs out that may carry ticks and fleas, but fleas and ticks could still be present in a fenced area. Spraying outdoor areas for ticks and fleas can further reduce the risk of ticks and fleas.

Another parasite that cannot be prevented by a dog's fence is cuterebra. The cuterebra eggs may be found on rocks or in soil and may be ingested during grooming if they get on the dog's fur. The skin of the dog may be penetrated by cuterebra larvae. - 29895
