Hello! What has it been for your dog with TVD? We just found out our 6 month old is a 5 out of 6 in severity. His left atrium is 2xs the size as the right side. He is perfectly fine otherwise. You wouldn't know he is sick. I'm just trying to understand how some live long while others don't. Please let me know your experience. Thank you.I'm wondering how Yukon is doing? We are experiencing the same thing with our now 11 month old puppy. He was diagnosed with TVD in October. The breeder knows and was appropriately upset. We have him on a diuretic but otherwise he is leading a normal life. We don't take him on major outings, but he does run on the beach or in the woods with other dogs most days. Our cardiologist told us that there are two places that will do surgery on this. One in CA and one in CO. The surgery is risky and expensive and the outcome is not guaranteed so we decided against it. We have decided to give him the best life we can for however long he has. Last night when I tucked my 12 year old in to bed he was crying because he doesn't want our pup to die. It's just so sad. I'm interested in how things will progress from here. I'd just like to prepare myself. Yesterday he vomited up both meals right after eating. There was lots of mucus in the vomit and the food wasn't digested. This is probably a result of eating too quickly, but when something like this happens I immediately wonder if it's a symptom of TVD. I hope Yukon is doing ok!
