Bad experience at the Vet.

I went to a vet one time with my joe dog they said he has heart worms and needs to be treated ... I said ok ...they gave me medicine to give him athome til time to do the treatment .......well meantime I got my other good dog poncho cut where his stomach lineing was cut and his guts was bulged out in his skin not outside just a fist sized bulge ...well I brought him to that clinic ...lady said whats wrong I said he's hog cut ...she said well we have a bunch of people ahead of you I said mam that sign right there says everyone waits there turn unless an emergency comes in emergencies go right in ....... she said well I'm sorry sir I said yes you are .. I went down the road to another vet and he took him in I told him he will bite if you touch it ...he said well lets put him down and he did ...before I got home he called to say he died ...man I have sewed up many a dog blowing air he was just so good of a dog I was scared he had a nicked gut ......took joe he treated him he died in a few months so man I just don't know .....I haven't had much luck bringing dogs in ....
