There are ways to spot dog worms and the best way is to physically inspect your dog’s stool.

Roundworms and Hookworms

Fully developed roundworms and hookworms will appear. The size can vary from small to large. They appear like spaghetti pasta that looks a little off-white. Practice caution and do not come in contact with the worms because they can infect human.


They look small and has an off-white to tan color. It appears to be a little segment in the stool. You should also look at your dog’s genital area. Tapeworms tend to cling to the hair around that area.

Fresh worms

Fresh worms are often white. They are about a quarter or half-inch long. What makes them gross is they can expand and contract. When these worms are dry, they will look similar to a rice grain or some dark sesame seed.

How To Prevent Dog Worms?

The most important part of protecting your pet lies in prevention – not on how you deworm them. After some satisfactory deworming sessions, your job as his pet-parent is to prevent worm infestation in the first place.

Prevention will always be better than cure. Follow these tips to help you safeguard your furbaby from those harmful worms.


Always keep in mind that a dose of preventative medication is the best investment for your pup. It’s not expensive enough to burn your bank. Medication is far more affordable compared to the cost of delicate operations that your dog might undergo if the worms get worse.

Physically Inspect Your Pet

Observe how your dog behaves and evaluate if there are changes that may indicate a bad condition. Hookworms, for instance, can sip your pet’s blood causing him to become anemic.

Check your dog’s gums. An anemic dog has gray to white gums. On the other hand, a healthy gum looks pale pink.

Vet Visits

Make sure to visit your local vet once a month. It’s also the perfect time to give your puppy his medication. Set an appointment with your vet for him to give your dog the right attention.

Apart from medication (when the infestation currently occurs), the vet can also give an annual preventive dosage for your dog when the infestation is still not imminent.

Preventive dosage can regulate the possibility of future parasitic infestation.

Habitual cleanliness

It may sound like a complete cliché but remind yourself that cleanliness will always be next to godliness. Always throw away your pet’s feces away. Put it in a plastic bag and dispose of somewhere inaccessible for both animals and children.

Make sure that his place is always clean. Disinfect the floors and change his bed sheets more often. Apart from parasites, you might also want to prevent or get rid of mites.

Controlled eating

Do NOT ever let your pet eat dead animals or play other pet’s feces. Be mindful of their early stages and train them not to dwell on these things – eating random things can be a pet’s habit.

Dead bodies and decomposing feces are the perfect environment for parasites to thrive. Getting in contact with these things dramatically increases the chances of getting infected.

Wash Your Hands

After cleaning your pet’s litter or getting in contact with them, wash your hands especially if you know they could be infected.

Make sure you wash your hands with a good anti-bacterial soap. Ensure that you’re able to tackle your nails, especially if you have long ones. Nails are also a conducive place for bacteria to grow.

Maintain Proper Hygiene

Practice a good hygiene routine. Start by keeping your house and backyard clean. When you spot some feces, get rid of them right away. Do not let feces stay longer than a day – it’s an opportunity for the parasite to develop and harm you too.
