I am chuckling here I just missed my forensic show because I got caught up in reading all 8 pages of this.
PMS must be going strong!! Now I'm just trying to lighten the mood. PLEASE dont' take me literally
Here's my 2 cents for what it's worth. Yorkies are a challenge to housetrain to begin with. When you have mutiple Yorkies in your home you are guaranteed to have some pecking order establised. I believe it depends on the personality of each individual Yorkie or other breed in the household. Some mesh well better than others, so to say exactly what the outcome will be is not possible.
This is what I do when I don't know the answer to something. I prepare for the worst, that way I will have planned ahead of how to deal with it. If things turn out for the best, well, who needs to prepare for that!
As for the altering of pets. I am a frim believer that all pets that are not used for breeding shoudl be altered. My vet uses a safer procedure for females to be spayed called laporoscopy (sp?). This is done by making 2 holes in the abdomen and performing the procedure while watching on a monitor. This eliminates the incision in the adomen and healing time. With technology these days there is no reason not to alter. The pros out weigh the cons.
I may as well through this in here. I feel there are more people that want to 'TRY' breeding. We are so incontrol of these innocent lives that we can turn it off an on if we want to and some do. That frustrates me that's why I do not get into the breeding aspect of these topics. Besides, the advise given is similar to what'd I'd give.
Hugs,
