what kind of dog should I buy?

Don't buy a dog, adopt a dog. Just go to the animal shelter and rescue one. In fact rescue two if you're concerned about a dog being alone all of the time. If there is another dog present they can keep each other company.

I suggest you go to the local shelter or rescue and look for an adult that fits your requirements. There are plenty around that are looking for a home, and you don't appear to be in a position to get a puppy as puppies cannot be left alone for that long. They really need to be taken out and played with/trained/given other stimulation at least every two hours and even that is stretching it. As a general rule how long a puppy can hold it is their age in months plus one, meaning a two month puppy can hold it maximum three hours, however it most likely will not and not being there to take the pup out when needed is going to prolong housetraining by weeks or even several months.

a chowchow =) our chowchow just lies down and waits. he doubles as a guard dog. LOL hes not lazy though if you take him out .. hes up to walking. he looks like a teddybear too.

in my opinion ,buy a pug ,its small,easy to handle, very popular,and has a good habit of following and obeying his master.
