I am sorry you are going through this. I went through something similar with a Siberian husky. She was 6. She was acting odd and had a puffy face around her eyes and was lethargic in the evening. She seemed okay during the day. I took her to vets and we kept trying to figure it out. I was afraid it was a brain tumor, but the vet said I should be seeing seizures. It turned out it was a brain tumor. I hope your Dakota doesn't have that, but my Misha had foot problems before the eye problem, so that's what made me think of her.
What I wish I'd done, in retrospect, was give her pain medication and prednisone much sooner. Narcropsy revealed the tumor was much too deep to have ever been removed surgically, so at most I might have given her radiation and comfort measures. I really loved that dog and it was awful to lose her so young, but sometimes there is nothing you can do.
I am so sorry to hear of Dakota's illness. It does sound like Ghilly has given you some wonderful options and advice.
May I ask if your dog was checked for dry eye....? My dog had dry eye. Keratoconjuctivitis sicca.....it is a simple test, done at the vets office. It is called a Schrimer tear test, and only requires a paper test strip.
Some of the symptoms are frequent infections, squinting, rubbing of the eyes, eyes may become cloudy or discolored, eye ulcers, and discharge from the eyes......it can also lead to blindness.
When you do get him back to the vet, ask to have this simple test done.
Again, I am sorry to hear about his current diagnosis....please let us know how things are going.

Wow, I am SO sorry that you and Dakota are going through this!
You don't say where you live, but if I were you I would look into any veterinary colleges in your state. They have state of the art equipment when it comes to diagnostics and even though veterinary students work on the animals, they are just inches away from graduating and they work under the close supervision of their professors, who are veterinary professors and doctors themselves.
As far as payment goes, look into Care Credit. Just about every veterinary hospital offers it and you can apply right then and there in their office. They can give you an answer pretty much immediately as to whether or not you are accepted.
You can also try this web address: http://www.animalcompassionnetwork.org/resources/1
It has many links to different sites that all offer some form of assistance for paying veterinary bills, hopefully one of them will be something you can use. Please let us know how Dakota is.
