I think he is around 10 lbs. He's a good size, not too small, but not too big! Bella is around 10 as well, and she is taller, but he is alot chunkier. Bella looks like a reindeer with long legs, lol. She's a little jealous, and she is lot more hyper than him. She was allll over him...jumping and sniffing, and he wanted nothing to do with her, lol. It will take a little bit of time, but Bella has always been great with other dogs, so I'm not worried. I walked in the house holding him, and I think that's what got her upset, because she's my baby. Charlie has to be the sweetest dog I've ever met, and I will spoil him to death!
