I have 2 Maltese/Poodles, one is 12 years old (whole dog)and one is about 9 months old (spayed). We got the second dog as the older one was getting lonely as my children were growing up and not home as much. They got along fine with the older one playing mother to the younger one even until the younger one was spayed then they gradually began to fight. I can't see any trigger for the fights and it seems to vary as to which one starts it. When it first started we used to pick the older one up and ignore the younger to try and make the older one 'top dog' but this seemed to make things worse. The younger one does follow the older one around for most of the day(very closely as in nose to tail, she has even bumped into her behind if the older one stops suddenly LOL) and copies her actions all day so it may just be that she is annoying her so much that she finally loses it. The younger one could just feel rejected and then reacts but I don't really know alot about dogs so could just be assigning human emotions to them. When they fight neither back down so we pick both up (luckily they aren't german shepherds!) and put them both in a separate room for 5 - 10 mins on their own as in a time out the way you would with children. They don't like to be away from us so it's the only 'punishment' I can think of as I can't bring myself to hit an animal. I didn't have a dog growing up so don't really know alot about them, can anyone tell me if we are doing the right thing or are we making things worse?
