In the last few months I've noticed Pasta hacking up kibble a lot, she's always done it but it's getting worse. It's all over the house, in the bedroom, kitchen, living room. You can hear her coughing when she eats and then she also usually does it on her way back to her bed after eating. She doesn't eat fast or anything, just gets it stuck sometimes. I've heard of senior people getting to the point where they need liquid food, is this something that should be done for dogs too?
