Our Igor has been vomiting clear mucus like liquid after drinking water. He has been dealing with this for 3 days now. He doesn't vomit if we give him small amounts of liquid, so we cut the amount of water in his bowl and just increased the frequency. What do you guys think? We've been hesitant to bring him to the vet because the last few times we've been there the vet asked us to run multiple tests every time like blood tests and xrays just to find out everything is normal. I know that's good news but it kinda takes toll on our pockets and some tests felt unnecessary.
