Something very important to know about Cheagles is that they are just as likely to want to play with your hands as they are a toy. They inherit this from their Chihuahua heritage. As fearsome as they look, they can be quite gentle. In this photo Henley has clearly opted to munch on fingers rather than her lamb toy, but she is applying a light touch as she knows it’s play and doesn’t want to hurt me. Sometimes entire play sessions will be dedicated to her trying to catch my hands before I can grab her paws, side, or tail; inevitably she wins.
Probably the most important thing to keep in mind is that your Cheagle should love you. If they love you they may express that love by wanting to play directly with you, instead of through a proxy like a toy. Fear not if this is what the Cheagle wants, it will certainly toughen your hands and strengthen your bond with your Cheagle.
