So we have had our new little girl Layla since Monday and we knew we were going to have issues with Bailey adjusting to the new addition. Day 1 we introduced them in the backyard and Bailey almost bit off poor Layla's ear.
Bailey has never been aggresive EVER! Not with humans not with other dogs, she has always just been a even tempered sweet easy going girl. But she must have sensed that Layla was not just a temporary visitor but a permanent addition and felt threatened.
We have been really good about giving Bailey extra attention and taking her for little walks and little car trips alone. On Thursday (day 4) Bailey finally could be in the same area as Layla without trying to attack her, Layla would run over to her and try to give her kisses and Bailey would just shun away from her and turn her head and ignor her or just run away.
Yesterday (Saturday day 6) Bailey began to jump into Layla's play area and play (or thats what we thought at first) but the more we watch her the less we think shes playing and the more confused we get. She runs around growls at her and then straddles her. Thats all she does pretty much is just get herself on top of Layla and stay there with her whole body on top of Layla, if Layla moves Bailey re possitions herself over her again. We are thinking this is Baileys way of asserting dominance but it just seems weird. I tryed looking this up and couldnt find anything on it.
Has anyone ever heard of this or perhaps your yorkie does it too? Do you know what this is?
Will Bailey EVER play with Layla like she does other dogs or is this as good as its guna get? How long did it take for your first to get used to a second addition?
I know Its alot of questions and I appreciate anyone that can answer any. Thanks in advance to all =)
