A member on another board of mine recently took in a foster puppy who was diagnosed with a very severe heart murmur. They're hoping to put her through surgery to correct the murmur and give her a chance at life, and they're asking for donations. I was sent a PMing asking to cross-post, so I hope that's ok! Her name is Echo and she's an 8 week old Cavalier King Charles Spaniel -- the first dog listed on the page when you scroll down. Please donate if you can... any little bit helps.
