I have a one year old, female. I got her at 6 wks old as my 8 year old smaller mix lab was grieving for her life long doggie companion had to be put to sleep. For the first six months the Labradoodle stayed in the laundry room and my older dog with me under the bed. When we returned to my winter home I keep the Doodle in a huge kennel here in my room. Every time I let her out she pulls on the tail or grabs the older dog by the back legs or nips at the neck. The older dog tollerates it as she knows the Doodle is just playing but it happens ALL the time. When will she just lie down next to the older dog and take a nap?? If I just let them continue, the older dog just looks up at me saying" Put her back in her kennel". When I give her freedom to roam, she goes outside thru the doggie door to poop just fine. But if I'm not watching her constantly she might come back in with the doggie door flap to chew on. During this "roaming time" the older dog is safe under the bed because her first choice is mouthing the older dog. Most of the time she is lying down, sometimes even on her back bitting on the Lab but it's still very anoying to me and the Lab. Do I just let them "duke it out" and hope she out grows it? I'm now walking them both together and she's good not to jump on the Lab during the walk but that's the only time. Any thoughts????
