Zub,

I am going to be pretty straight forward here.

You are being your own worse enemy. Your wife has no reason to respect your wishes or meet your needs. She suffers no consequences of her actions. Pretty much she knows you are not going to do anything about it.
You don't want another dog may run through her mind. Along with well if I bring it home whats he gonna do about it nothing. So why not. Same with he wants to have sex but if I dont meet that need whats he gonna do about it nothing. So why should I.

What would you do if you told your daughter that she could not have a friend over and yet she still shows up with one in tow. You told your daughter she could not go to a party because there would be alcohol there and she still went and came home drunk. If your daughter knows you will do jack about it except talk to her. Odds are she will do what she wants. But if you take the keys to her car ground her for a month or so forth shes really gonna stop and think before she does if she wants to suffer the consequences.

You don't have to leave. But you can run a add in the paper for free dogs. You can not only say but enforce the fact that animal care is not coming out of household expenses that she is soley responsible for them since she choices to have them. You can also check state and local laws of how many animals a person is allowed with or with a a kennel license to how much space/acerage. Ie one to two horses to 5 acers where I live. None allowed with less then 5 acers. 4 domestic animals per household. If you find there are ordinances about this you can simply let her know it has been brought to your attention that you are in violation of this and that she needs to take this into consideration because it could cause the loss of all the animals and fines if she keeps exceeding these laws.

Or you can simple swallow the pill and take any new strays to the human society (not pound). And tell her from her on out every new animal she brings in you are going to remove this way. Though she has the right to bring them you also have the right to not be forced to live with them.

There are a million different things you can do about this Zub. You just have to decide to do it. They may not be comfortable but is living with a house full of unwanted animals anymore comfortable.

Simply put if I had a job and knew I could still get paid and not have to show up for work everyday because I would not get fired. Do you think I would not take advantage of this. You know there is a great sale at Kohls today and since nothing will happen to me if I don't show up Why not go to the sale instead.
