My Nigel went to dog heaven, about five hours ago! R.I.P.

I am still reeling; and so missing him!

My Nigel went to dog heaven, about five hours ago! Because of a misdiagnosis on September 4th, when I rushed him to his Vet because he was bleeding … excessively, from somewhere! Blood was everywhere on my floors. I, eventually, was told that it was from his toe, where he had snagged it on something. He was, supposedly, treated, AND sent home with pain pills and an antibiotic. I called the Vet back on the 5th, then the 6th because he was coughing, sneezing, hacking … making funny gagging noises AND it was getting worse. I was basically told that I was being a worry wart; AND told that it, most likely, were allergies. The nurse stated that she will leave a prescription at the front desk; AND for me to pick them up on Tuesday, since they will be closed Labor Day. This morning, my dog was shaking and making funny noises, etc. I found an emergency veterinarian clinic, that was a distance away. Took him, where they told me he is already gone. I broke down.The Veterinarian there told me that he bled to death! That other vet killed MY dog! Quacks!
