Bad Cough and Hard Breathing

Hi I found this forum while looking for help for my dog. She’s a mixed chiwawa. I have no idea what she mixed with. She is going to be 15 in September and around the middle of June of this year she had a seizure, which only lasted about 10 to 20 secs.

It’s been about 2 weeks since then and she has had around 15 or a little more through those weeks but they have stopped but since they have stopped, she has a cough now that is slowly getting worse. It kind of sounds like she got something stuck in her throat. Like a hair ball, she trying to spit out but she coughs for about a min and then swallows whatever it seems she tries to bring up.

I can’t really afford any kind of vet at this time. So I’m not sure if this will pass like the seizures did or maybe as much as I don’t want to put her to sleep. Today was her first time not eating but I can see why since today was the worse of the coughing.

To add about her life style. She does not go outside she is a inside dog she’s been outside maybe 4 times in her life because of the times I have moved to different places other than that she a inside dog who does her business inside as well.

If theirs even such thing as a free vet or at lease something for poor owners please send me some info. I live in New York City and I've try Google but no luck so far.

Thx for any replies
