How come people say milk is bad for dogs?

2 stories: My husband had a dog when we were dating about 9years ago. He found the dog laying on the ground taking his last breath almost dying and growing up people told us when a dog is sick give them milk. My husband gets the gallon of milk ,opens the dogs mouth and makes the dog drink it. After 5 minutes the dog gets up, almost falling but gets up and starts walking. That dog died of old age. Another story: My small female chihuahua was coughing and vomiting and I gave her milk, within a few minutes, I no longer heard the cough and she stopped vomiting. Do my dogs just have strong digestive systems or what? Or does Milk really help sick dogs?Just wondering if anyone else has used this on there sick dog?

Dogs a lactose intolerant that's why

Dogs and cats do not have the proper enzymes to properly break down the sugar in milk which is called 'lactose.' You may have heard of people who are lactose-intolerant. They are also missing these digestive enzymes. If the proper enzymes are not present, the lactose remains undigested and tends to ferment in the intestine and cause diarrhea. Some pets can tolerate a little milk, others, none at all. If your pet enjoys and appears to tolerate milk, you can give your pet small amounts. Better yet, give your pet one of the special cat or dog milks on the market that have had the lactose removed.

I think it has to due with the fact that many dogs are lactose intorlernt. So having dairy can cause them upset stomach, cramps, gas and vomiting. Just like us humans, some of us cannot diegest the sugars in the milk, yet others have no problems.

It is not bad in moderation. It can cause diarrhea if they drink too much too quickly. The occasional sip or two won't hurt them.

Dogs are supposdly lactose intolerant. My dog drinks milk all the time and he is 10 now and living a healthy life. I think milk calms stomach acid like it does in humans which is why a dog would do well to have some. I think that it just depends on the theory people live by...I say whatever works for you.

may be the kind of milk u used with ur dog is not good or expired

milk is bad after a dog digests it... it usually gives them diahrea and dehydrates them. so you should probably give them lots of extra water afterwards just in case.

cause it gives them the squirts
