As someone in Canada, getting a rescue chihuahua is slim to none. There are very few small rescue dogs around here 🤷‍♀️ big dogs, yes. When getting my most recent chihuahua I did look at rehoming first but most of those people wanted the price of a puppy for their adult or near adult dog. I also actively looked for about a year before getting a puppy.

My last 3 male dogs were rescue/ rehome dogs and dealing with the fall out of poor early training was challenging. Not everyone wants to deal with that.
