It’s a sad fact that many dogs entering animal shelters are malnourished and underweight. It pains me to see animals struggling to the point where they’re almost too weak to stand.
Some, in spite of their neglect, remain affectionate and trusting towards humans, though others shrink in fear when a rescuer approaches. What the latter have been subjected to sometimes doesn’t bear thinking about.
Personally, I can’t imagine ever wanting to hurt an animal. Furthermore, I simply can’t understand why anyone would take any sort of pleasure in doing so …
