Sorry I dont agree. These were perfectly healthy animals taken from shelters where they had a chance of being adopted, promised to be given good homes, and then injected with drugs they most likely obtained illegally.
You can see where that is coming from?
Besides which, what do you think the shelter does with animals that cant be adopted? They euthanize them. Legally. But at least they give the animals a chance to be adopted first. So what is gained by speeding up the process? Absolutely nothing.
Shelters dont give dogs to testing labs, or skin them or anything else like you are talking about. I've worked as a volunteer in both city pounds and Humane Society shelters. If you believe for one second that they would ever send animals they collect to such a place, you are sadly misinformed.
