I have one that will mark if something is new that she is jealous of. She never has accidents in the house but when my mom's dog first came to visit she went right over to her crate and peed right by it. She has done it in similar instances as well. Tinkerbell will sniff around for a spot in the grass and swing her butt around to get it in just the right spot, same spot everytime. So yes I think they definately do mark! |
