I'm so sorry for the loss of your Dani, lawrie. Any
animal can have an unexpected and lethal reaction to anesthesia. It does
happen...but it doesn't make the event any less traumatic or tragic.
I don't know that vaccination on the same day as the microchipping. What is puzzling to me, though, is that sedation was used at all. Here they just inject the microchip under the skin with a needle and no sedation is necessary....
