My dog's problem is similar to the one just published. Our dog came back from the kennel throwing up. The kennel told us he threw up a few times this morning before we picked him up. He drank some water when we came home with him early this afternoon but has since thrown up a few times (drive heaved once tonight). He hasn't eaten anything or drunk anything (so far as I know) from the time he drank some after we came home. He is lethargic; just sleeps and rests. He has no other symptoms (no coughing for example).
