Dogbreedinfo is a GREAT site! When I take the breed selector test, the majority of my list are herding dogs.

I can understand about the dog costing too much. For instance, we are able to pay for dog bills and such but if Kai cost 2000 up front, we may not have been able to pay for the first month (or at least, we'd struggle a bit). If you truly want this breed, save up. Just wait and maybe while you're saving, you find a better breed for your lifestyle.

There are shelters you could go to and still find the perfect dog. Mutts are great but if you're fixed on a boxer, you can also try local boxer rescues.

The list of prices Wolfsoul listed are pretty accurate. Here's what we paid this month alone:
Vet:40
Neutering:100
Toys:10
Food:50
Obedience class:110
Treats:20
Flea control:40
Total:270
That's just this month alone. I didn't even include the crate, leash, collars and id tags.
