That's sad, because it's trivially curable, supposedly. Man, if they'd snip those male dogs' with a vasectomy, what an improvement it would be...same here north of the mexico-us border.
Sure, but who pays for spaying and neutering the plethora of street dogs in the poorest states in Mexico? And many people have dogs without the means of paying for this (or any) kind of surgery.
Between us and my MIL we have 10 dogs, and all of them except one are fixed. I've made sure of that. I'm not able to win the argument over the last one, but it's old now anyways. The dogs she had that got sick was from before I was in the picture.
