What is the cause to vomit

Stoniphi said:
Not necessarily. The paraquaductal grey region is supposed to dampen pain signals, but sometimes in some people is does not do that. A migraine headache, severe shoulder pain, an inner ear balance problem and a bunch of other things can overwhelm that brain area such that the pain resonates in waves of pain signals that wash back and forth through the area like waves of water in a bath tub until the person vomits.

There are other things that can make you vomit though. Trying to swallow a raw egg or drink something that tastes very bad, eating something that produces too much stomach acid..those will all make you vomit as well. They involve your sense of taste, your sense of smell and your stomach's ability to know when its contents are too acidic to process are all different mechanisms that can lead to nausea.

I would bet that the pathways those stigmata take into your brain are all different as well.

I will get back to my dog. It is well known a dog have one of greatest sensors of smell. I take it the sense of smell is a gas chromatograph , were it identifies a variety of compounds and the organism identifies pleasant and unpleasant.
My Puch, liked, ham, cold cuts chicken . hot dogs . ( everything is identified by smell ). come time , hot dog no good any more, the followed by cold cuts, than ham, and ended with ham and then nothing any more . Then if you force ( mildly )he will vomit.
So this becomes a signal some thing in the system is wrong. Since the system is based on circulating fluids, some compound is introduced with time into the system in larger quantity until reaches a threshold.: then some part in the brain will signal the involuntary reflex to initiate the reverse peristaltic action. So the question is what is the growing compound with time and were is it produced.
 
If you cut the tissue out of a human nose and spread it out flat, it would be about the size of a handkerchief. If you do the same thing with a dog's nose, it would be the size of a full double-sheet of newspaper.

More than 50% of the cells and synapses in a dog's brain are devoted to his sense of smell.
 
We spell it "pooch".

He may have a problem other than what you think. For example, he could have a stomach ulcer or a tumor in his stomach or even something stuck in his throat, like part of a stick. He could have a problem with his gall bladder or even his kidneys. If you have access to a veterinarian you should take him in for a checkup instead of trying to figure it out on your own. That is what I would do.

You seem to be looking for a simple answer, but it might be more complicated than that.

I appreciate your input. But I am far beyond your suggestion ( veterinary ) It. I had cost me over 1000 dollars, and my Pooch is death at the veterinary , I went through speculation of poisoning by neighbors, and others . So thank you for your comment. Result from veterinary based on x-ray . liver, kidney, I have concluded based on vomit material more rational then the vet.
 
I understand, you have my condolences. :frown:

The possibility of an enemy poisoning my dog terrifies me as I live in the city with many people, though I get along with most of them. I watch when she is out in the yard, and my neighbors know that I am potentially dangerous to antagonize being a self-defense expert as well as being tight with the city and police here. Also, a sheriff lives next door to me. :wink:

My Yellow Labrador has had 3 surgeries for mast cell sarcoma, a type of cancer. That has cost me a couple of thousand dollars, but she is still healthy otherwise and with me. I guess one could say that we are both living with cancer.

Have you considered asking the vet for an autopsy?

We live in a suburb on 2 acres. Our dog (a 12-year-old Lhasa Apso) is neither big enough nor energetic enough to need a large yard. We have a small patch of the lawn fenced in outside the back door, and that seems to be all he needs. Once in a while I put him on a leash and take him for a long walk, closer to the perimeter, so he'll understand where our boundaries are. He enjoys it, but doesn't beg for it.

In any case, it would be difficult for anyone to poison him.

Our cats don't go outside, period. -- If only because a pair of eagles occasionally land in our yard!

I can understand a 12 old dog is more restrained , our was a 5 year old Alaskan Malamute, weight 162 Lb and with energy,
 
We are in a corner house with a picket fence about 10 feet from the side wall. On the other side of the fence is the sidewalk, and we get a lot of foot traffic past the place. My Yellow Labrador weighs 90 pounds and is a very beautiful lady. Not much of a guard dog though, she is more of a lover. :smile: She is especially fond of little girls who spend a lot of time petting her through the fence.

I have kilos of that stuff, Dave. :wink:
 
Uh...that would be a tremendous deal for you, wouldn't it? :D Unfortunately, I need it for work. :cool:

Best price I found recently was about $5/gram for decent material from a reliable source. You gotta watch out for the stuff that was blasted out the mine as it is chock full of cracks. Gotta have it in hand to check for that though...
