I just thought of this and didn't know who to ask. What happens to petstore puppies if they don't get bought? I was buying stuff at petland (I hate to support them but its the only place that sells the cat food I like), I noticed there was a xoloitzcuintli. Where I live, hairless dogs are considered gross, and the cute fluffy poms and huskies will for sure be bought, and the xoloitzcuintli is noticeably older than all of the other puppies... Do they put them on sale?.. or worse put them down?
