I started this group, but my girl isn't a purebred Rottie, she is a Rott/Pit Bull mix; however, there are a lot of things that she does that seem to be things that other purebred Rotties do.
1 - She likes to side bump other dogs
2 - She chews her own nails (no, not in an unhealthy, see the vet, kind of way...she actually seems to "self groom" and I've never once had to cut her nails)...I've heard of a few other Rotties that do this.
