Rocky had a bit of a rough night last night. He started gagging and I'm wondering if it's related to reintroducing kibble (softened) to him. I wasn't able to get ahold of the oncologist last night, but left a message. In the meantime, I found some research about humans undergoing radiation therapy and sometimes people have trouble with swallowing during radiation therapy that leads to gagging. I wonder if that applies to canines as well.
