I was doing my one month practicum at the SPCA and realized that they were a much nicer place than what everyone says they are. The only animals that were euthanized were dogs that bit a human, more than three times AND seriously, cats that were sick and hadn't gotten better in more than one month, and seriously injured animals. When I was there we only euthanized two dogs. One was a 17 year old JRT that was having heart failure and a pitbull X named Seth who bit my friend (another vet assistant) and 3 SPCA employees. It was hard, but this is life. Someones gotta do it, and sadly I had to assist in the euthanization.
