Im having a hard time with my jack russel she's 8 years old and hasn't been eating the past 3 days it was very sudden and I've tried numerous amounts of things, changing her dog food, wet food, chicken broth, flavored water drinks, milk and tuna. I'm running out of ideas. Any input?

Take her to a vet.

She could have gotten into something and swallowed it, she could have a blockage. I used to see it all the time at the vet's office I worked at. Get her to a vet soon

The vet is your only option, and I recommend you go yesterday, two days ago would be better.

There's really nothing we can do. She isn't eating, that's a sign that something is very wrong. Only your vet can give you a diagnosis, and hopefully a treatment. The only other option, and I'm not trying to be harsh, is to watch her die of starvation.

Vet! Please! Find a way. That's the only option you have.

I hope that it all works out. I know the pain of losing a fur baby you love.
