Our Dog, Delilah, just recently went to the vet and we learned she has a large tumor near her heart. The vet's say its a 30-50% chance that the treatment will work.
They said are our options are:
A) Perform surgery and if she doesn't get better, put her to sleep
or
B) Put her to sleep now.
We have been considering putting Samson(Her companion) down as well. His heart rate has been a lot slower now, he only gets up to go outside or eat. Otherwise, he just lays down.
Should we put both of them to sleep for the best of it or is there another option we can consider?
