It looks like a rat with really long legs... Remember dogs have snouts.
Actually I'd keep that model, looks good for a "minor creature from hell" model.
Ryans right, look up dogs and take a close look at the snout/muzzle. The rest looks okay. In my opinion, it could use some extra polys to smooth it out a little. Right now, it looks too blocky. You should also look at dogs fur and eyes. The texture is off on those points.
It's got good basic shape except for the head, so keep working on it!
Im still trying too make that GTA in FPS game and heres a model
i need someone who would texture it for me
Thanks
I have it in object format only send me a message and i will give you the link. Also i used some advice every piece of the object is separated into a few parts
Fix up the snout + add a few more polys to the feet and it'll look good.

[EDIT]There are a few problems with the legs, but not too bad. You also should work on the texture.
the head is to round, fix the legs because they look to crooked thats all i have to say, *BUMP* any responses to my mp5
It still is a work in progress, i don't really need a dog in my game so ill keep it till i need a dog (or a rat with long legs...

)
The texture is just a stand-in till i want to texture it, thanks for the feedback.
Bradamente, can you post that soldier in non workmode?
My MP5 is 537 polys i think i could do better but it doesn't have a texture therefore its ugly. Second it is only a test since I'm actually adding to the model if you know what I mean. So thanks for giving me that information its very helpful. Oh and I need a few scripts for aiming/zooming in, blood on the dead bodies, etc. And it would be helpful if i had a second modeler, a script maker and editor in general. Thanks, Kingdaura
