Why is that the condition of animals here is literally the worst?

I visited my nani's place after half a decade and what shocked me to my core is the condition of animals. Be it rural village or shining cities, it's all the same for them. All dogs are nothing but a bag of bones. It was a shock to me to see dogs literally panting and running around for water, I was having kachori and saw a cute pup, I offered him one and he literally gulped it down. Like I haven't seen a dog having anything other than milk, bread or dog food. I wanna know is it because people don't like em and see them as pest or is it something else? Even Buffalo and cows are left to die?
