My puppy's poop has white strings and mucus. Are these worms?

Congrats on your new puppy! I'm wondering if you mean a deworming treatment for intestinal worms. Heartworms aren't treated by antibiotics, it is treated by Immiticide, nor are they seen in the anus. Heartworms reside in the blood vessels around the heart and lungs. You may be seeing roundworms in Alvin's anus, which can happen when a dog is being treated for intestinal worms. He needs at least two deworming treatments given two weeks apart to kill all the worms. If you don't think it's intestinal worms, then I would have him seen by a vet to diagnose what this white string is so he can be treated.

These are roundworms. They are a common parasite for puppies to acquire at birth and don't tend to cause any major problems. They are easily treatable with deworming medication that can be purchased at a pet store, or a veterinary office. I recommend having a vet prescribe the medication to ensure it's safe for Oreo and proper instructions are given. I hope that helps and all is well with Oreo.

The number one reason for puppies to have diarrhea with mucus around it is intestinal parasites (worms). It is best to take her to the vet for an exam so they can run a fecal test and then treat her accordingly.

Thank you for submitting your question regarding your puppy. He will need to see his veterinarian today. He potentially has round worms. However, fecal testing will be necessary to confirm this and to determine if there are any other parasites presents. It is common for puppies to be infected with more than one type of parasite. Based on these results, medication can be prescribed. I hope this information helps!

This is likely not a big ordeal especially since she is acting Norma and the poop has been normal since but I would contact your vet to see if you could have her fecal checked to ensure she doesn't have any intestinal parasites that could be causing what sounds like mucus in her poop. If this continues then I would urge you to have her examined to find the cause. I hope this helps.

This is a roundworm indeed, you need to go to the pet shop, you should be able to find a puppy dewormer there, it should only take a few days until your puppy is worm free after the treatment is given.

This sounds like she may have intestinal worms. I recommend using a puppy deworming treatment dosed carefully for her weight and repeated as per directions. A probiotic is also recommended to promote recovery. If she develops a fever or loss of appetite she must be seen by your vet
