NO!!! This is NOT close to being NORMAL......YOU HAVE AN EMERGENCY!!! Sounds to me like he has been poisoned!!!
If so, you don't have time to be searching the internet!!! PLEASE, get him/her to the VET ASAP...You need to make the call, now!! You must hurry!!!! Please, come back & let us know what you find out...Good luck....
Your dog seems to be very sick and I suggest you get to your Vet ASAP!! It could be a number of things from Parvo, something he ingested, etc.
please get him in to be checked as this sounds serious and please come back to update. Good luck!
