Dancer did this so often when we first got her that her nickname was The Puke Hound. :lol I asked my old time Vet about it and he said to give her a Tums. He also said to raise her feed bowl and see if it stops. Well the Tums worked, but shortly after we got Dylan and we also got raised feeder/water bowls. Dancer stopped the puking most of the time. Sometimes she would tank up on water when she came in from a potty and still do the burp/puke thing, but if we slowed down her drinking she wouldn't do it.
