I posted a little while ago about really wanting a puppy - we got one! He's an 11 week old chihuahua / mini pinscher mix. We named him Zeus Almighty "our last name".
And it really has been a good bonding experience with the step kids. They're in love with him, and it's such a big "family thing" we did together (they picked him out and helped come up with the name). I feel like it helped us make progress towards becoming a family - or at least more towards me feeling like it is one!
The last photo is Zeus playing with a dog that we're baby sitting right now.
