Name something that weighs ten pounds

Guys should I adopt this dog? Here I three reasons I probably should.

1. My landlord said he prefers if I don't have pets BUT he said it so gently that I think he would love this one.

2. Last week I saw a free fish tank WITH FISH on Craigslist and before I had time to decide good idea or bad idea it was gone. So maybe from now on I should assume everything is a good idea.

3. He looks like Paddington. The dog does, not my landlord.
