How to get rid of Giardia in a dog?

If your vet is no longer able to help I suggest getting a second opinion.

You've got to be extra careful and clean so the dog doesn't reinfect himself.

But really, if your vet can't figure out what to do, then I'd be off to a different one. Giardia for 8 months can't be a good thing.

Add - no runny stool with mucous? Or putrid smell? I mean dastardly putrid odor? I would still go to another vet and get a confirmation of this. It sounds weird. Carrier means he can pass to other pups and you don't want to be responsible for that. So make sure you vigilantly clean up after him always.

More than likely the dog is reinfecting themselves. If some of their water supply is outside where other animals can get to it ( especially birds), that can reinfect, or eating bird poop also can cause reinfection. So look at the environment and decontaminate the ground where the dogs poop and where wild birds might have access, And put the water to where you can prevent wildlife from gaining access to it and clean that daily . Also do your dogs play in ponds, creeks, and rivers. That is another source of potential reinfection .

Adult dogs may not have symptoms but be infected . So all the dogs have to be treated unless you get stool samples showing the other dogs don't have it. .

Hope this helps

If you have other dogs, they should be treated at the same time. I'd treat for coccidia as well, since for some reason they seem to go hand in hand. I've had fecal exams run have them turn up positive for giardia only,and fenbendazol seems to do nothing even after prolonged treatment. I then treat with albon, and problem solved

albon is another medication that is sometimes used to treat giardia, check with your vet to see if they are willing to prescribe this medication. I an assuming that the vet is doing fecal floatation's to check for this intestinal parasite. there is always a second opinion form another vet to make sure that your dog is suffering from giardia. hope this helps

Have your vet refer you to a canine internal medicine vet for another opinion.
