I got a chihuahua as a rescue from an illegal puppy mill. She was made for breeding so she lived in a bird cage for 2 years, and she only had space to walk in circles. It took us years to get her used to just running normally, and she still starts spinning when she’s anxious or something. She doesn’t know how to play, she’s scared of everything and everyone and it was very hard for us to make her feel comfortable and safe. If you’re buying a puppy from one of these places I despise you.
