Pets in Japan

So you have just moved to Japan and are feeling a bit lonely. Not to keen on a Candy Girl or a Tenga cup, you seek to buy a dog.
How much are you willing to pay for one? How about 98,000 yen (870 USD) for starters to get this little fella above?

Or if you have a bit more money then how does 168,000 yen (1500 USD) sound for this French Toy Poodle below?
I'm not knowledgeable about the price of dogs at all but they seem pretty expensive to me. After some research, I found that Bulldogs are the most expensive costing between 230,000 yen and a whopping 450,000 yen (4000 USD) (source).

Or if you would rather get a bit more value for money then how using that 450,000 yen to get 450 rodents (1,000 yen each) to run about your house. Dont forget that these are a popular pets to have in Japan too if you are on a low budget. Do you own pets? Are dogs expensive in your region?
