Hi know this might be a stupid question but my puppy doesn't really wag his tail that much at all... He wags his tail when we enter the room and sometimes when he's being fed, but that's about it. He's 15 weeks old, we're pretty sure he's a puppy mill pup, we got him when he was 10 weeks old. He seems to be a happy little thing, he plays all the time and does great with training too, but even when he plays his tail stays completely still exept curl up over his back when he's walking and running (he's half cav half bichon). I was just wondering if this is normal or if it's something we should worry about? Does anyone have any experience with this?
