My 6 week old, Twinkle: The Little Star, was diagnosed with Hydrocephalus.

I noticed that she wasn't acting or reacting like her litter mates. She was born with a Mohawk. Her head is misshapen, more horse like & has an open fontanel (soft spot). She would cry out. When I was holding her one evening her eyes began to flicker & twitch & then drooled very heavily. I think she had a seizure. She may also have visual problems. I researched the symptoms online & to my dismay, Hydrocephalus kept popping up. I took her to the vet & as soon as I walked into the room his face cringed & stated that I have a very sick puppy. We talked & I asked if I should put her down, so she would not live a painful life. He said that she would probably die of a seizure & as the disease progress, so would the seizures & that I would know when to put her down. He suggested a neurologist to do brain surgery. I'm not going to put the baby through that.
If anyone has experience with a puppy in this condition, I'd appreciate it. I am contemplating putting her down so she doesn't suffer.
