My 9 yr old LionHead has begun sneezing (almost quacking, not sure if it's a sneeze or a cough) He had no discharge, his eyes are clear and Vet did not hear anything lower respiratory. As a precaution he had a round of antibiotics but it has not made any difference. He is acting his social self and eating, drinking and pooping. I limit pellets in order to encourage his Timothy Hay. My vet did not see anything major with his teeth though he said it could be at the root level. At his age I am afraid to do anything too involved. Does anyone have a suggestion as to what to do? Has anyone been through this with their bunny and how did it progress? What can I expect ?
