Need some help
My dog is 16 years old and he is about 60lbs. He is a mut that we got at the local humane society. He has been a WONDERFUL dog. He has recently started to lose his hearing and eye sight, which is to be expected with such old age. The thing that I am concerned about is that over the last couple days he has been throwing up that yellow foamy frothy bile stuff. I have read some of the other forum posts about dogs throwing up this stuff but he eats(when he actually gets up out of bed to do so) and drinks just fine. But each time he does throw up its only the yellow stuff, nothing else. He has also started to act like he is starving all the time, more then our other dogs. Most days he runs around like he is a puppy still and plays with our younger dogs with no problem but the last couple days he has been just kinda blah. He contstantly pants also, 24/7. We dont know what to do or why this is happening so if anyone could help us out with some feedback or suggestions that would be wonderful!
