Wow! I'm so glad that I found this site! I'm a mom to a 10 month old yorkie girl named Tiffiny. She is such a sweetie! I also have a 2 year old mini daschund and before recently, they got along pretty famously. Last night, my daughter and I were playing around and all of a sudden my girls were going at it. Tiffiny was obviously the aggressor and when pulled from my daschund she fought to get at her again. I settled the situation and put the girls back down and Tiffiny went after Dutchess again!! I finally got the situation calmed down but for a while after, my Tiff would put her front paws up on top of Dutchess, I'm thinking it was to show her domanance over Dutchess. Finally things went back to normal. Poor Dutchess, for a while she looked so sad! From reading the previous posts, my daughter's and my play initiated the situation. Maybe she is coming into season? Any thoughts would be appreciated!
