That is a very fallacious argument.
By this logic, all humans should only care about the most pressing problem. Good thing for you and I humans don't think like this. I rather like that someone invented cough syrup for when I'm sick, Advil for when I hurt, and jeans that are more comfortable than their predecessors.
All of these were trivial in the global sense but because one or some human(s) championed a cause cool shit got done for the globe.
Let others champion their causes, you yours. No reason to ignore a problem just because there is a bigger one. (By that logic we better start working on the sun going Nova in a few billion....)
At least in America, there are lots of states starting to ban, or propose legislation that bans, mass breeding of animals for sale.

My cats first owner was an old gentleman who passed and the family surrendered her.
She was taken from a kill shelter to a non kill shelter, adopted once, re surrendered, then adopted by me, within 72 hours. Sweetest 6 year old striped tabby, that just jumped on my lap when I went to pick a cat.
Information on raising dogs is readily available online. Most people have no excuse for not knowing how to care for a pet. Unfortunately, pretty much all the problems spoken about in this thread come down to irresponsible people, and one cannot force someone to be responsible. While punitive measures sound great, I think it would be rather challenging to enforce them. Attempting to sway societal perceptions around pet ownership is probably the best solution, but that's a massive and slow undertaking.
