Because your dog's tummy is upset for some reason. You need to take your dog in to be checked out by your Veterinarian. Bring in a small stool sample from your dog with you. It could be something simple like indigestion or a symptom of something much more severe such as Parvo, Salmon Poisoning, etc. That is why it is best to take your dog immediately in to see a Veterinarian.
Uhh... yeah I would take your dog to the vet...
your dog would throw up and crap everywhere

A dog's mucus plug typically appears as a thick, clear to slightly cloudy gel-like substance. It may be somewhat stringy and can vary in color from transparent to slightly yellow or pink. The plug forms in the cervix of a pregnant dog and is usually expelled shortly before she goes into labor. If you observe this, it indicates that the dog is nearing the time of whelping.
the dog might throw up or he'll be fine
Mucus
It doesn't sound right. I would have a vet check it out.

It would throw up. It can't eat human food.
How can i find out if the pink mole on my dog's foot is ment to be there??????
There is no pink dog, but there is Birdo, who may, or may not be a turtle.
Hot pink seems extreme..... If your dog is hot pink you should see a vet. (Like myself)
