I don't know what your wife will dislike the most. The intial price of the dog or all the toys that come along with it. I look at it like this, the least expensive thing you will buy is the dog itself no matter what the cost is. You have to feed, vet bills, crate, training toys etc. I will try to break down my dog cost for you to help you out and I am not throwing dollars at you to scare you away.
Dog Stand $180
Vet $30-80 depending on the visit, I have to keep mine on flea med all year because of where I reside.
Misc toys $100
I know if you add all this up it seems like a lot of damn money, but I have accumulated this stuff slowly. I also was able to work alot of it off because of the kennels I worked at. Good luck with your search.
