Some of you might remember that my girl Molly has a small mass on her breast. Well, Luke, her son, who's 5, has a large mass on his bladder. We've been going to the vet about once a week for a month due to problems with him not being able to control his bladder, blood in his urine etc. His bloodwork was fine, but he's been losing 1 - 2 lbs every week. This is a Sheltie who's usually about 35 lbs, and he's down to 27.6. Today, the vet felt a mass on his bladder that wasn't there last week. Thursday, he goes in for surgery. I hope to god it's just a tumor, non-cancerous. Please pray for my pup.
