It depends who you ask. When my parents come to visit they both get on me about how neglected Bear is and how Pig is clearly my favourite. My sister makes fun of me when I talk to Bear, telling him how he’s the absolute best dog in the world, unlike his demon spawn of a sister.
In reality I do more with Pig. She goes out with me far more often and she goes to class every week, I work her much more than I do Bear. But a lot of that is just because of their temperament/activity level differences.
Bear can be DR and is somewhat SSA, so if I know there are going to be other dogs around I leave him behind so he doesn’t get stressed out. He’s also not as into training. He will try to do anything I ask of him if there’s a ball involved, but it’s almost like he’s thinking “why can’t you just throw the ball†the whole time. Pig loves working for working’s sake. Yes, she’s doing it because there is a reward in it for her, but she also seems to just love working things out. So yes, I enjoy training Pig more but a big part of that is because she enjoys it more. Bear is my boy though and I will forever be his person.
