I would have to strongly agree with Traciek88- I fell into the same trap and got a Boston Terrier because I loved my first one. She is pretty unlike my first Boston aside from looking somewhat similar, farting a lot, and liking to cuddle (which are both very strong Boston breed traits, and there's not a huge amount of physical variation in the breed either). She has a completely different energy level (the first one would sleep all day given the chance, this one is off the wall energetic), doesn't bark where the other one was a great watchdog, is much more trainable, and is obsessed with strangers and other dogs where my first was standoffish. I've actually ended up liking this Boston more than my first, but if I'd had this dog first and gotten the second Boston because I liked the breed I think I would be disappointed.
I would also agree that dog looks like a mutt. I'm fairly good with dog breeds (having a special liking for researching rare breeds) and I've never heard of that breed at all.
In terms of breeds that remind me of him in looks I'd guess Staffordshire Terrier, maybe Bull Terrier, Ibeazan Hound (in coloring and ear shape), maybe Miniature or German Pinscher. All these breeds are very different, however, and some fit better into the average household than others (for examaple, a Staffy is a great all around dog but an Ibeazan Hound isn't for everyone). I can almost guarantee you he had no Ibeazan Hound in him, they're a rather rare/specialized breed to be showing up in a random mix. Staffy and Bull Terrier are pretty likely, I think.
I would agree with making a list of all the things you loved most about him and then going to a shelter and looking for a dog that fits those traits.
Also, you say you're just moving out- that makes me think you're fairly young and possibly not done with school yet. As someone who is 20, still going through school. and has their own dogm I would caution you to think very carefully about what dog you bring home. Getting a problem dog in your 20's is a lot more of a bummer than when you're more settled. Think about things like how hard it will be to find housing with that size and breed mix, don't go for a dog or breed that will have trouble with long hours alone because at this point in your life you just don't know if you will need to leave them for a long time, etc. It can be great to have a dog at this age but it takes a certain level of maturity, dedication and smarts to get the right dog for your situation because it's a lot harder to deal with issues in school (if you are still in school this may not even apply to you) than it is during your working life.
