Where hookworms latch onto organs (and they can go further than the intestines actually) -- and Sandra's description of them as little vampires is pretty close, except they are virtually ALL teeth (the whole parasite is almost one big mouth filled with teeth -- nasty nasty buggers), whipworms are like little razor blades - they slice and then feed off the blood they let.
If a dog gets a bad case of them, which can include older animals, or animals generally not in wonderful health -- it doesn't take long to kill them. You'll often hear many of us say that one of the first steps when you suspect an animal is ill is to check the gums to see if they are pink, and to check the "capillary refill time" by pressing the gums hard and then releasing to see if the color snaps back right away (within a second or two) -- these things can help a vet over the phone detect that there might be such serious parasites.
Sandra is also correct that because heartworms are IN the bloodstream there is no way for them to get out in the stool -- think of how the body works. Food in, goes to stomach, passes thru to intestines and kidneys.
Blood circulates thru kidneys and liver -- in order for blood to 'filter' waste it goes thru the liver (which doesn't excrete waste well) and to the kidneys (which exits thru urine). This is why you have to keep heartworm dogs so sedentary for so long -- because it takes the body a LONG LONG TIME to process the dead parasites slowly and safely breaking the dead 'bodies' down sufficienty for them to become 'liquid'.
Think of what a stroke is in humans -- a blood 'clot' right?? What causes a blood 'clot'?? Any thickening of the blood or any bits of stuff that breaks off inside a blood vessel (that's why arterial surgery in humans is so risky if you think about it) goes sailing thru the blood vessel to 'clog' it up if it takes a wrong turn.
This isn't to scare anyone -- but Sandra is totally 100% right -- vets often don't tell people enough. So people sometimes don't take enough precaution to keep the dog sedentary thinking "oh, it's been a couple of weeks now SURELY they're dead!!" Well, yeah, they are and that's where the danger zone begins!!
But given time and rest the body CAN take care of this.
But once again I'll say something unpopular and say heartworm is so much more easily PREVENTED than it is treated. I'm honestly glad that these ladies have taken the time and effort to post about their dogs being treated, cos it AIN'T easy and it's hard of the people and very hard on the dog.
I lost a dog to hooks/whips (and he hadn't been anywhere but in MY OWN yard, but I'd taken a foster briefly during a hurricane who brought in the parasites, Mike got them and was gone within a month before I even knew he had them.) and I've helped a dog thru heartworm treatment. I hate having to give my dogs chemicals to prevent heartworm, but I'll do it to prevent having them be treated. The odds of a dog getting one of these parasites is so much higher than winning the lottery it's not funny. I don't play the lottery. I do use heartworm prevention.
(Dang soapbox hasn't gotten THIS kind of use in a long time. Sorry!)
