dogs tummy

Question
On the day after thanksgiving a toy manchester terrier came and adopted us.  We have not gotten him to vet yet so I don't know how old he is, I do know he is not a puppy.  anyway, a few weeks ago he started throwing up.  He was only doing this when on our bed..so we thought was allergic.  put him in crate at night (he hates it and I hate it) and it stopped.  we thought maybe he just wasn't feeling well for a while ..so we let him back in room in his own little bed.  He did it again.  I changed his food to purina sensitive system.  tonight he did it again only in the living room.  and again in his crate a bit later.  am very confused and since I have always been a cat owner I am at a loss.  Could you please give advice.  Yes I know we have to get him to a vet but financially not feasible at this point.  he is not fixed so that also has to be done.  Thank you for any help and advice that you can give.

Answer
Hi Stacey!  Congrats on your new addition!
Unfortunately, his symptoms could be the signs of MANY possible ailments.  It is impossible to even suspect anything without a physical examination, being that we don't know the age and history of this dog.  It could be allergies, an obstruction in his intestinal tract, a foreign body in his intestinal tract, Irritable Bowel Disease, liver problems, ect.  I understand completely that a vet visit isn't financially feasible at this time, as diagnostic procedures can be very costly, but unfortunately, a vet visit is what this little man needs.  I would definitely suggest talking to your veterinarian about a payment plan, as most are willing to work with you, or at least hold checks for you.  I wish I could be of more help.  Please let me know how he does.
