If you have a dog or puppy, you may have found yourself in this scenario before: your dog is doing her routine number two during a walk, but when you reach to scoop the poop to throw away you notice thin, stringy, white things in her stool. Unless your canine companion recently ate some very fine thread, chances are, your dog has worms. Passing worms through her stool are one sign that worms are leaving a dog's body, but you'll want to make sure to seek proper medical care to make sure any intestinal parasites are treated and exterminated.

Dog worms treatment

If you suspect that your dog or puppy may have intestinal worms, you'll want to visit your veterinarian as soon as possible to get an official diagnosis and get started on a dog-worms treatment. Often, dogs with worms won't display obvious symptoms but sometimes signs do make themselves apparent.

Banfield Animal Hospital states that diarrhea, blood, or mucous in the stool, scooting, weight loss, or general irritation, like licking the area around their butts, may indicate the presence of worms in a dog or puppy. Sometimes you can even see small worms in a dog's stool, like roundworms or hookworms, which resemble spaghetti noodles, or tapeworm fragments, which look similar to grains of rice.


Treating intestinal worms is fairly easy once the type of worms inside him have been identified and your dog has been diagnosed. Banfield also explains that intestinal worms can be treated with a dewormer, which is given either in liquid or pill form. Your veterinarian will be able to decide which dewormer will be needed to treat the specific types of worms in your dog and will also consider additional factors like his age and overall condition of health before prescribing one.

Over-the-counter dewormers are also available, as are homeopathic remedies, but it's recommended that you visit a veterinarian first to determine which type of worms your dog is infected with if you're going to self-administer medication.


Physical signs of improvement

One sign that worms are leaving your dog's body are the presence of worms in her stool, as mentioned above. Some worms won't be seen as they dissolve inside of dogs, but others become paralyzed by the medication and may be passed out through stool or vomit. Additionally, an improvement in overall health and physical appearance can indicate that your dog's dewormer is working and that worms are leaving her body.

Blue Cross for Pets lists a swollen abdomen, lethargy, coughing and dehydration as common symptoms of worms, so a decrease in bloating or an increase in energy or water and food consumption are generally a good sign that your dog is headed on a healthy track.


Adverse reactions to dewormer

Dog dewormer, when prescribed and administered correctly, is generally free of side effects, but sometimes a dog reaction to worming tablets can happen. Common side effects of dewormer include vomiting and lack of appetite but if these symptoms persist take your dog to a veterinarian immediately.

If your puppy still has worms after deworming, it may not be a cause for concern depending on where he is in his vaccination schedule and the number of rounds of dewormer that are needed. VCA Hospitals states that puppies should be administered vaccinations on a regular schedule from around 6 to 20 weeks of age in order to protect them from possible infectious diseases.


During this time, be sure to keep your puppy away from social places, like dog parks and kennels, and take care to avoid other dog's stool, which could be contaminated and reinfect him. If you've completed your regimen of dewormer and your puppy still has worms, revisit your veterinarian for a recheck, which may reveal additional and different worms that weren't treated by the previous medication.
