World War 3 over Bully Sticks!

[mscat]

I brought home 2 Bully sticks for both dogs. Suzi our 19 month old yorkie , and Miely boo our 4 month old Shih Tzu puppy. They have had Bully sticks before , no problems!
tonight, was a completely different story Suzi decides Miely's Bully stick is better then hers , so she goes for it. However , Miely is not haven it . SHe turns aggressive , and it was a horrible fight between the 2. Miely was extremely peeved , then , Suzi was not given up either. This happened 2 times. the first time my son and I quickly intervened , and showed Suzi where her bone was. She went back to it. Everything seemed to have been resolved. Not more then 10 min. later, Suzi tried it again ! this time Miely let out the most horrible, aggressive noise I've ever heard .Suzi still was NOT backing down!
Luckily, I was right next to both of them , and tried holding the puppy back, she was still going peeved though, but small enough that I could control.
We took Suzi in my bedroom with her Bully stick , and left miely out with hers to chew on.
OMG, to think about it, if we were not here to stop them from fighting!!! I thought i did everything right! giving them their own Bully sticks? However, Suzi still wanted to take Miely's away. Miely fought back though, and it was the first time their has EVER been a fight between these two .
Any suggestions? Besides the obvious? keeping them apart when they have their special Bones, however, I have not seen the puppy ever react like this to Suzi. Suzi is always trying to take Miely's toys from her, every time she has one. This time , it was frightning !
I hope this NEVER occurs again between them . Miely is smaller then Suzi, I guess Suzi thinks she can boss her around? Was this a dominence thing? Or what ?
None of my babies were hurt during the scuffle, thank god. I am going to HAVE TO supervise them now and forever with their bully sticks, putting them away when I can't ! these 2 are like little children .

Unfortunately, that's what will happen a lot of times, but especially between two unspayed females (I kind of remember you stating Suzi was not spayed before, I think).

Dogs are so weird -- they always want what the other dog has, even if they have the same exact thing. Jackson is the same way. I take him over to my dad's house with two other dogs and we give all three of them the same bone(s)... two of them are ALWAYS staring at the other dog wanting THAT particular bone. There have been a few fights over there, mainly by the female Lily (Jackson and the other dog are males.) If Jackson even gets 2 feet away from Lily, she will attack him. So, there's definitely been a few brawls over there. Lily (like Suzi) also lived as an only dog for the first year of her life so I think that's part of it too. She never had to share before. I've that learned that female dogs are called bitches for a reason! LOL. My mom's female dog who passed was the same way with her bones.

Basically, I think with two dogs it's bound to happen. I think it's going to happen more with two females just in my experience. But I would recommend getting them both spayed asap because that will probably (not a guarantee) help with aggression.

Mine do the same thing! I do not let them have them in their crate. They love sleeping together & I just started that this week. They are sweet and loving to one another UNTIL you bring in a chewie. They havent hurt each other but I always stop them. Baxter thinks they ALL belong to him.
