The side effects of deworming a dog is vomiting, diarrhea, lack of appetite, or just general queasiness a couple of hours after they receive treatment, it is normal. Depending on the severity of the infestation, the side effects will vary. If the infestation was bad, the side effects might last a few days. We are talking about parasites inside your dog.

It is understandable they may not be feeling so hot as the worms proceed to make their way out of your dog’s system. If the symptoms are still bothering your furry friend in a week, you may want to check in with your vet to ensure there is no damage being done.

It sounds horrifying, yet it is so normalized. Puppies are dewormed on a schedule to ensure health, starting at 2 to 3 weeks old(1). A critical but often overlooked aspect of being a dog owner, this is one of your duties of protecting your dog. If you aren’t vigilant with your dog’s health, it could end with their demise in the future.

What Is Deworming?

Before we get into discussing deworming, let’s clear up a common misconception: the treatment for removing worms is actually called worming and not deworming. It is a mistake a lot of people make, but this allows us to move forward with new knowledge. Our new-found knowledge prompts us to instead ask, “what is worming?”

At birth, many dogs can already be infected with the troublesome worms. This is because their mother was also infected with worms. She passed them on to her offspring in utero, or it could be passed on through her milk after birth. It is usually symbolized by puppies with bloated, hard stomachs. Worms are so prevalent in dogs that newborn puppies are put through a routine of worming sessions to ensure their health. As puppies grow, they will receive their first worming at 2 weeks, the next at 4 weeks. From there, they receive worming treatments once a month thereafter until the pup turns six months old. This is to keep your puppy safe as they develop into their adult selves. [1]2

Puppies aren’t fully developed until they reach 12 to 18 months of age. Keeping them healthy during their youth is important! [2]3

Dog worms are so common that the outside ground, particularly the grass and dirt, is a hot spot for the parasites looking for hosts. The parasites are generally passed through stool or vomit, and then they will stay alive in the soil. If your dog walks over an infected patch of dirt and licks its paw soon after, the infestation of your dog’s system begins.

What to Expect and How Long Worming Takes

A considerably simple method, worming treatments can be reduced down to the size of a fly. The tablet your canine will digest provides assistance with eliminating parasites such as roundworms, whipworms, tapeworms, and hookworms.

Most of the parasites listed are intestinal parasites, but the heartworm is true to its name and affects the heart and lungs. [3]4

When the treatment is taken, it will be a few hours before the effects of the medicine begin to work. When they start to work, they are disabling and paralyzing the parasites in your dog’s system. There is no exact timeframe for the healing time, as it varies based on the severity of the infection and your dog’s overall health. Worming may not be completed for a few weeks and need more than one treatment.

After the first dose, you should wait two weeks and check in with your vet again. Your vet will test your dog’s fecal matter; if there are still parasites found, another dose will be advised. If you do not go to the vet and have another dose, it is always advised to call a vet and consult them before giving your dog any medication.

My Puppy Is Tired After Worming Treatment

If your puppy is sleepy after a worming treat, don’t be concerned. Puppies have only been a part of this world for a short time and they only have so much energy to give. Medical situations are stressful for many dogs, making that exhausting by itself. Adding in the element that parasites in their body are about to be forcibly expelled, you have a combination that equals fatigue. Be patient and kind to your puppy during these times. They are still small and deserve all the rest they need.

Did you Know?

Puppies tend to sleep between 18-20 hours a day! With how much developing they’re doing, any action takes a lot of energy from the young pup. [4]5

Worming Tablets

Worming tablets are available from multiple providers, but they do the same thing essentially. The tablets work to disable the parasites so the dog’s body can properly eject them. While it may seem miserable for your dog to be experiencing gastrointestinal issues after worming, it is better than the other option of letting the parasites stay in your dog.

There is the possibility of overdose with worming tablets, but this is generally when fed in a large quantity that is 10 times the recommended dose at least. This shouldn’t happen unless there is an accident, but you can put the medication in a hard-to-reach place to protect your dog!

Can I Give My Dog A Bath After Worming?

When your dog has just gotten a worming treatment, it is best to allow them to relax. Your furry companion may be experiencing issues with their stomach and gastrointestinal system. Some dogs have a fear of water or general anxiety over bath time. These nerves could make your dog even more prone to gastrointestinal problems. You may have a mess on your hands if you are not prepared.

If your dog is a dog who finds relaxation in baths, it is something that you can consider, but note that there could be an accident if your dog gets too relaxed. Their systems aren’t at 100%, meaning they may not have full control of their disposal.

Some people use topically applied preventatives for worms. If you are included in those people, you do not want to wash your dog for at least 24 after applying, though 48 hours is recommended. [5]6

Conclusion to Side Effects of  Worming a Dog

While there are side effects to deworming your dog, it is still crucial to do so. The risk of having parasites cause significant problems would be disastrous and it needs to be controlled. If your pup is tired for a few days, you can rest assured knowing you are doing what’s best for them.

If your dog doesn’t seem to be feeling any better after a week or they seem to be worsening, you should contact your vet. Your dog’s behavior is a huge indicator of if something is wrong, so be sure to pay close attention to them after receiving the treatments.

Even if your dog hasn’t been displaying any symptoms, there is no reason not to treat and prevent the paradises dogs can get through their life. Do right by them; they will appreciate you.
