First of all, welcome to EBN! Sorry you had to find us under such a bad circumstance, though.
I'm so glad to hear that Samson is doing better. That's such great news!
My bulldog, Delilah, developed pneumonia this past winter. She was about 1.5 years old. It was absolutely awful. I almost lost her. =/ She couldn't breathe, was running a really high fever, no appetite, her heart was pounding and beating way too fast..it was just awful. She was so terribly dehydrated. I had to take her to the ER vet 3x in one week. She went to the regular vet about 3x that week. She eventually ended up needing hospitalized for four days to get her better. I was SO scared i was going to lose her. She wasn't coming out of it and they said, "There's only so much you can do. You might want to consider the other option." No way in hell was I putting down my 1.5 year old dog over pneumonia!! Luckily, she got better...$1500 later though. =/ I hope it's been easier on your wallet. I'm so glad Samson is better. It's so terrible when the babies are so sick.
