I am so very sorry to hear about this. 6 years old is way too young! Had your vet heard a heart murmur in the past? Usually, that telltale waterfall sound of SAS is something the vet can hear during an exam. Something else to consider is Hemangiosarcoma, a painless but lethal cancer that is oh so very and sadly common in goldens. They can go so fast that way too. Whatever the reason, losing your 6 year old golden like that is a nightmare, and I hope all the good times with him are the images that stay with you now. What was his name?
