About two weeks ago Elvis was due to have his tetanus/strangles booster and I left my Stepdad to do the injection as I was getting ready to leave. I showed him were to put the injection in Elvis's. When we got home it was dark just thought Elvis was blinded by the headlights so he was walking slow. The next morning my Stepdad rushes back to the house for me to ring the vet, Elvis isnt too good. I asked him 6 times where he had injected Elvis "In the bottom part of the neck" was his reply. It took about 15 minutes of Elvis turning away from me for me to get a halter on him even with a carrot. I could not see any swelling on either side of his neck and was just about to go ring the vet when I found swelling on his near side shoulder right in the middle where the leg and shoulder bones and muscles all connect. I rang the vet and he came out and checked Elvis out, he said he was in a lot of pain and his heart rate was 40 bpm and gave Elvis painkillers and antibiotics (left extras for 7 days). Finally my question, he doesnt like being tied up let alone have anything syringe shaped near him (I am slowly working on this) and I want to worm him, would you do a feed or molassis water etc. Sorry its so long.
