Found cute small dog - Houston, TX

Hello - I thought I'd post here regarding the little dog we found last Saturday. I suspect someone dropped it off as it appears to be well cared for but was in the back of my son's p/u truck with a collar/no tags. It's too small to jump in it on it's own. It's a male, 22 pounds and mix breed (I think). It's young but appears like it's not going to grow much more (it's feet fit!). It's affectionate and smart. I already have two male dogs and all those males are having issues amongst them. I really need to find a home for this little guy. Photos are at: http://s3.photobucket.com/albums/y91/clauskr/Found%20dog/ If anyone recognizes the breed and could tell me, that would be helpful. Thanks.
