In human first aid, tourniquets have recently come in for catastrophic bleeding. Now, a tourniquet is a strap that goes around the limb, so any one of the dog's legs, that will go around it, and it actually cuts off all circulation beyond that point. The important thing with tourniquets is they will go around, they will grip quite tight and they first cut off venous supply, the venous return back to the body, and then they cut off the arterial blood flow. It is quite important that you put it on tight enough so that they stop both the venous and the arterial. Otherwise, you will actually speed up the bleeding process. With that said, there is no research currently on whether you use tourniquets on pets, so really, this is just linking to what you may be hearing on human courses as to what you can do with dogs and cats and other animals.

This is a commercial tourniquet. The thing with these are they are definitely not designed for dogs. Now, we have had some research with people in the military side who have said they have used it in life-threatening situations. However, with a dog's leg, it is quite easy to get hold of it in your hand to physically stop the bleeding with direct pressure or using something like a haemostat. The problem with something like this, it is designed to go on a human arm or a human leg, so they are far too big. On the back here, there is a plastic part to actually get that to grip properly around a small animal's leg. It will not work, so be really cautious about using something like this on an animal. Far better than using a tourniquet would be to use a haemostatic dressing, which we cover those in a separate video.
