I know this is stupid...but I'm soooo worried about my baby. He's getting neutered and having his teeth cleaned. He only weighed 3lb 11 oz when they weighed him ( he's almost 3yrs old), and it hit me that this little guy is going to have SURGERY!

Also the Doc said he has a heart murmur, and that lots of little dogs have one...wtf? this is the first time anyone mentioned a HEART MURMUR! Has anyone else heard of this? does anyone have any advice or experience with dogs and heart murmurs?
Geez, I'm soooo darn worried about my little Lupo
