Too many people thinking let's have a kid, but not thinking about all the "crap" that comes with kids! Too put it bluntly!
I've bought 2 pups over the last 2 years due to the loss of older dogs! BOTH were said as house trained, HA! The one came from Spain 4.5 month old, NONE of the litter were trained, the entire litter also came complete with worms and other lovely issues!.
The 2nd pup, bought last year, when I asked the owner if she were house trained, of course!!
Was she hell!
I got her house trained in a couple of weeks, the owner when we contacted her, "what's it matter, just mop it up like we do!" She has hard floor, we have carpets !
Parents CAN'T & SHOULDN'T use the excuse that they don't have time, they wanted the kids, they should make time. It's NOT the schools responsibility to potty train kids.
