My own personal opinion is that hookworms in dogs are the most devastating and hardest worm to kill.
Hookworms are small and invisible to the naked eye, but usually, their symptoms are not!
Dark black, bloody diarrhea, poor weight gain and growth in dogs, and weakness can all be signs of hookworms.
Hookworms consume a lot of blood and can leave your dogs anemic, and in some cases, can cause death.

What most people do not realize, is that nothing can truly prevent this.
Dewormers only kill the hookworms in dogs that are in the intestinal tract, but do not affect the larvae. So though you worm your Golden Retriever monthly, and even do a fecal test before breeding, the pups are still going to be born with worms.
The larvae lays dormant in female dogs until pregnancy, then they become activated again and pass through her uterus to the puppies and also through her milk glands when nursing.
This is the reason to start worming puppies at the young age of 2 weeks, irregardless of whether or not the mother has “active” worms.

Wormers with the ingredient, pyrantel pamoate, is an effective hookworm treatment. It is a safe wormer and will do a good job, as long as you use it correctly.
Pups need to be wormed with this every 2 weeks until they are 10 to 12 weeks old.
It is liquid and the dose goes by weight, so make sure you weigh your pup before every worming to make sure he is getting enough of this medicine.
Nemex 2 is an excellent dewormer that gives great results. However, if you have a large litter of puppies it can get a bit pricey.
The Evict Brand is a good product at a slightly cheaper cost. Do keep in mind that since Golden Retrievers are large breed dogs (and puppies!) that if you choose the Evict brand, you should buy the DS, which stands for double strength.
This way it lasts longer as you do not have to give as much per dose.
Another thing to consider when treating for hookworms in dogs is to wait a bit before starting heartworm preventative. I like to wait until my pups are about 3 to 4 months old.
I use pyrantel pamoate every 2 weeks until they are 12 weeks old, and then start them on heartworm medicine the following month.
