I have a golden who is 7 1/2 years old. The last 2 nites he has woken up during the nite and made sounds as though he is choking or vomiting. He asks to go outside. Eats grass then comes back in. Nothing comes of it. He did however vomit once.) He seems to make these noises right about the time it is about to rain (I noticed that today as it was raining he was choking again.)
Does anyone know what the cause could be? I'm thinking aniexty but not sure and nor do I know what to do next.
