Can you give dogs dewormer even if they don't have worms?
Most dewormers for dogs are very safe and do not have much impact on the system other than to do their job and make sure the dog doesn't have worms. Your pooch can pick up worms anywhere, anytime even in winter and the can then spread said worms to your yard and track in the eggs in fecal matter to your home.
Should dogs be dewormed on a regular basis?
Every time you give a deworming pill you get rid of any adult worms that are living in the intestines. If there is a large number, you may see them pass in the stool (they look like a pile of spaghetti). Currently, we recommend monthly deworming for all dogs in the summer months.
Is dewormer harmful to dogs?
They're poisonous to pests, but safe for pets. Because worms are so common in puppies, vets recommend de-worming them for the first time when they're 2 to 3 weeks old.
