Kidney destruction resulting from improper exercise

I have read in several places that treadmills that create too much resistance can harm the kidneys.

I can't understand why, and in fact, I'm not convinced that this is true. It seems a lot of human exercise programs use a similar kind of resistance combined with cardiovascular. Aren't sled dogs subjected to the same kind of combination?

I'm willing to be convinced that I am wrong.

 

good question id like to know also

 

ive never heard that and yeah it seems that a sled dog would be even more subjected to that if this is true. ill be checking back on this thread

 

Is that question the same as people are saying that carpet mills ruin kidneys period ?

 

I have been told that you need your dog empty before his work out. Or it would increase the chance of kidney troubles.

 

Empty your dog and warm him up before using any mill, go as far as to change the feed schedule on the dogs you are working so you KNOW they are empty. Make sure they are hydrated but not with a belly full of water and monitor their work the ENTIRE TIME they are on the mill. It is a proven fact that to little work is better than to much. Heres a pointer for the newbies, when your dogs tongue spoons out at the end the work should be stopped and the dog should be walked out until breathing is back to normal. If your dogs tongue falls out the side of his/her mouth you have ruined your keep and the dog should be rested 3-7 days.

Dehydration and overwork cause kidney damage, not resistance from your mill.

thx for that and another question is it possible that a to heigh protein in the food has to do with it?

 

I have heard that myth but have not seen it occur in any of my dogs although, to high of a protein can cause intestinal bleeding. Higher protien dogfoods have been known to strip the intestinal lining because of how corse protien is (almost like fine sand). To understand this better take a pinch of creatine and chew it, it has the same consistancy as raw protein.

now that makes more sense to me

 

The high is a factor in kidney failure or "renal failure". But that is not it all in itself. It has more to do with those who leave their dog on a mill for long period of time without allowing the dog to excrete waste; waste that needs to be excreted from a high potien and mineral diet that promotes ketones sent to the kidneys. The same can be said for dog that are put on a high protien diet without enough workout time. The increased rate of motility from exercise demands the need to expel waste. NGK makes a very good point on the other effect of high protien diets that is why is is imperative to put a dog on a "natural high protien" diet. And don't forget plenty of H2O.

 

thank you.

 

Might have something to do with excessive muscle breakdown leading to excessive amounts of myoglobin in the blood. This is harmful to kidneys and can lead to short-tern and long-term renal failure.

 

Muscle breakdown and too much/too little protein, and dehydration is what affects the kidneys, not the actual physical excertion.

 

Excessive exertion specifically when exercising at high intensity for extended periods can lead to muscle breakdown. If this scenario is repeated too frequently in the face of dehydration myoglobin-induced renal damge occurs. Similarly, excessive muscle damage from traumatic injury can cause the same. It is the release of myoglobin that casues the damage. Note: I am speaking in reference to the human animal. On a side note, in humans, dietary protein has not been shown to have deleterious effects on renal function even in those with diminished renal function. Anyway, not fussing, not arguing, just offering a potential explanation.

 

OK my 2 cents. A treadmill CAN be harmfull.It is the best condition tool there is to get a dog in shape period , but at the same time can hurt your dog, when a dog is not been given a pre keep and ore is out of shape and ore comes of the chain and is workt hard, then there is a good chanse of heurting his kidneys .

ofcours a dog needs to be hydrated AND emty.. as NGK mentiond a dog is indeed OVER workt when his tongue curls up, but is NOT ruined YET.. inbetween culred up tonque(spoon) and ruin is a brief momend you can save him from being ruined. the momend of a dog being ruined starts when they are loosing asesif amounds of fluid out of his mouth!!!
then its over in a way you can forget about him doing work for a long time..

also a dog should be free of internal fat. to mutch fat shows up when he starts to fome out of his mouth!!. never push a dog that still fomes. its running them HOT and have the same afect his tongue is close to curling op
Personaly i have never had a dog with kidney failer being workt on a mill ore any other ecserzise, but i agree with NGK in saying LESS CAN BE MORE. most people today STILL look backwards what the oldtimers did. putting un nessersary 90 day keeps on a dog doing hours of mill work ecetera. This is wat is ruining most dogs

Ok consirnig high protien everyting above 33% protien with LESS then 20% fat and the needed carbohydrates is bad for your dog in training. let along given when doing nothing on the chain. only pups and pregnand bitches ore bitches in pup should be given high contens of protien
Protien poisioning shows itself when a dog gets dry skin and gets bold sports and becomes intolerend. his urine is dark yellow.
this should be avoided at all times.
dogs on the chain should not be given more then 22% protien and 12% fat . when winter comes incease the fat contese NOT the protien.
a mildly ecsersized dog should get no more then 27% protien and 15% of fat

Just asking, an orijen pdf but why at the bottom it says "Proceedings, 1998 Purina Nutrition Forum" are they members of the same mother copmpany?

 

What?...oh...never mind....

Here's a short and dirty explanation,......heat stroke and dehydration.
You see, kidneys are blood filters constantly working to remove dangerous waste from the circulatory system and moving it to where it can be safely excreted from the body,....usually as urine.

Let's say you put a dog or human on a treadmill and keep them running with no clue or common sense about overheating the core body temperature or about keeping either runners properly hydrated.

Slowly, but surely bodies become hotter and lose fluid through respiration, sweating, etc. As this happens, blood in the circulatory system thickens,......for example,....mix tomato sauce with water and pour it through a /collanderstrainer.....a lot of the water/sauce will through,...some tomato bits get left in the strainer/collander. Now dump your sauce/water into a pan on low heat and leave it for a while......the sauce heats up, water evaporates and the sauce thickens..... Pour this sauce through the same strainer/collander a scond time.....and nothing gets through....everything stays stuck in the collander.

Basically, that is what happens with over-work, over-heat and dehydration,....the blood thickens to a point where the kidneys (collander) can no longer filter the waste (tomato chunks) from the blood (sauce/water mixture) while allowing it to flow properly.

We call it kidney failure,...but it is more accurate to think of it as acute blood poisoning. It isn't that the dog isn't being given enough chances to excrete waste,......the dog just can't exrete even if it wanted to,....and that is what kills it.

Why does this happen in some situations more than others?
Well, some folks swear by certain "drying out," and other water restrictive methods with dogs in keep.

Now, you couple that with exercises that most dogs enjoy and seemingly do forever without showing signs of trouble/over-heating, dehydration....cat/carpet milling etc,....and you have a recipe for acute blood poisoning,....or.....repeated kindey damage. You see, the dog doesn't always drop the same day,.....but think of what happens when you constantly stretch a rubber band to its limits then let it snap back just in time day after day after day. One day that rubber band just pops before you even start stretching it. If a dog/human runs a marathon every day without proper rest or hydration sooner or later the constant damage to the kidneys becomes too much,...and one day they just stop working,....the rubber-band just pops.

On the other hand, if you build the work load slowly and keep hydration foremost, plus feed in the proper way....the body slowly learns to operate at higher than usual/normal core temperatures, the kidneys become strong enough to handle the thickening blood (temporarily),.......and the dog/athelete can handle contests that most others cannot.

 

great question and great anwsers. this forum is a great benefit.You guys are making me want to get back in the dogs.

 

NGK's explanation does make sense.
