Ever so often my schnauzer will cough up pflem. He has allergies and I have to give him Benadryl ever now and then. He is worse in the summer. What can be the cause of the pflem? He will sometimes vomit and that is all that he brings up. Is this due to the allergies or is there something maybe in his diet? He eats kibbles n bits and has ever since he was a year old. He is now 7 years old.
Is your dog vomiting bile or counghing up phlem??? I do not think you know this so I recommend that you bring your pet to a vet for a check up. If your pet vomits bile once in a while I would not be terribly concerned but if occurs daily then this could be a problem such as inflammatory bowel dz. Good luck, vetcare
